For every genre, there are some songs which might not be technically brilliant, but there is something about them which makes them addictive and a favourite for the repeat button. It might be a certain guitar riff, or a particular lyric which sticks in your head. Or it might be that the entire song is so relatable that you can't stop listening to it. Before you know it, you've clocked up ninety-seven on the play count, and you didn't even notice that you'd started singing the lyrics perfect, word for word.

Adele's album 21 had a number of these types of songs; the most obvious being Turning Tables Someone Like You. They're both simple songs comprised of a few chords each, they feature memorable choruses and there's a lot of repetition. As a result, they're easy to remember and should be top of the list for this type of music. The syncopated rhythms in Turning Tables also gain marks for being addictive in a sophisticated and complex sort of way.

For rock, you can't beat a bit of The Pretty Reckless. Make Me Wanna Die was at the top of the UK rock charts for several weeks. And for pretty much the same reasons listed above – it's not trying to do anything drastically new. But it's a great catchy tune with a very varied accompaniment (the ensemble includes pipe organ and strings) and flowing lyrics which are easy to scream when you're dancing in a club.

Finally, there is no way you can talk about catchy tunes stuck on repeat without mentioning the queen of such material – Lady Gaga herself. Having attained an almost God-like status over the music industry, her music is played every day and every night, throughout thousands of clubs, bars and shops all over the world. It's easily the catchiest music around at the moment, with songs like Poker Face and Bad Romance leading the way in popular music.

For some people, perhaps members of an older generation, it is unthinkable to put gospel and hip-hop in the same sentence. But the reality is this new trend is fast gaining popularity. It was previously unheard of to sing anything other than the age old hymns in the praise of God, or in the preaching of the gospel to convert others.

The phenomenon of other genres being integrated into gospel started around the 1980s, gospel hip-hop was pioneered then by artistes such as T-Bone, Stephen Wiley and MC Peace. One of the big breaks for gospel hip-hop came about in 1994, when Toby Mac co-founded Gotee Records, the first record label to exclusively market Christian hip-hop and R&B. The label marketed this contemporary Christian music at Christian bookstores and through seeking airplay on Christian radio stations.

Other record labels soon copied, dedicating themselves to gospel hip-hop and helping these rappers seek a broader market. But they faced a problem. Most of their sales were only to people brought up in the church. The hope, which had not been met, was to encourage prospective members of the community to join the church.

In recent times, rappers have become more accepted by both those who did not grow up in the church, as well as the by the conservative church goers. The latter were perhaps converted when they realised gospel hip-hop brought people, especially the youth, back to church as it was something they could relate to.

It has always been said that to be a musician takes great talent, commitment and heart. Most of the time people go into the music business possessing only the talent- said to be the most important aspect. Although it is true that talent is a necessary ingredient, one sure does need heart. This is because despite the glitz and glamour there are so many dark sides to it. Once in the public limelight privacy is thrown out the window, the occasional fashion faux pas days and leisurely walks on the street become things of the past. The right to choose what to wear, where to be, who to date and even who to marry, becomes strategic decisions that are decided upon by so called managers and agents.

This immense pressure propels some musicians towards drugs and an early death, sometimes through suicide. Take an example of recently deceased Amy Winehouse; the young lady had talent no doubt, but so much pressure from different quarters pushed her into drug and alcohol abuse. She got stuck in a rut, a place where even her incredible talent could not drag her out. As her music is still being played on some radio somewhere in the world, she rests at last in peace. Alcoholic poisoning the coroner's report said and it is such a sad reality that the world has been robbed of her music. Her case however is replicated all through music history. Cases like Kurt Cobain; whose suicide was attributed to struggles with drug addiction, Jimi Hendrix who was said to have died of asphyxiation, but had a tumultuous life coupled with drug addiction, Jim Morrison and Janis Joplin who supposedly died of drug overdoses and had struggled with addiction for a long time.

Weird as it may seem in order to qualify to be a hip hop artiste, you need to have served a stint in jail. Many successful rappers from time immemorial have had trouble with the law. But the hip hop world is truly a world of second chances; it has given a chance to previously incarcerated artistes to make a comeback in the industry. Lil Wayne, even when imprisoned on charges of weapon possession, went ahead to win numerous awards. His incarceration did not even cause a decline in his album sales, if anything they sold more.

In clear hip hop fashion, a blast from the past has recently declared a comeback. Mystikal, the fast rapping MC, known for his almost comical style has recently signed with Birdman under Cash Money records. After close to seven years of incarceration, the 41 year old rapper, whose real name is Michael Lawrence Tyler, was released in January 2010. The hit maker, known for hits like danger and shake ya ass, was jailed in 2004 on charges of sexual battery and extortion. To add salt to the injury, in 2005 while serving his sentence, he was additionally charged with failing to file tax returns for two years- attracting another year long jail term.

Other rappers who have served time in jail include T.I, who was imprisoned on felony weapons charges and drug charges but like Lil Wayne, his album topped the charts even when he was in jail. Maino, -who went to jail as a teenager on charges of drug related kidnapping, was later released and immediately signed to Atlantic records without a previous music career.

The 90’s were the glorious days of rap music. When the great MCs still walked and the rap game had its masters. This is when worldwide acceptance of hip hop was at its peak. The artistes from that era were those that had grown up listening to old school hip hop from rappers like Run DMC who served as their inspiration. Most of them had a history; this gave them something to rap about, topics that their audiences could relate to. They rapped about life in the projects, losing friends or family to gang violence, love stories in the hood as well as their everyday struggle to survive and to make it out of the ghetto.

These real life experiences kept them relevant, because there was a message in their music. Its often said that with time comes growth, or at least change and true enough, as the world moved into the twenty first century, the face of hip hop and rap changed. Buoyed by the struggles of their predecessors, a new crop of rappers came up whose rap message was different. It revolved around glamorous parties, multiple cars, female groupies and money. They had achieved the life that the older rappers yearned for. Rap was no longer about the message; it was about the beat of the music and the lifestyle. Many critics have dismissed this new hip hop as diluted, having incorporated various other genres of music like Rock and Soul music into it. Some critics claim that what is in the market nowadays is just ‘bubblegum rap’ and is completely baseless. They say rap has become too commercialized.

Hip-hop has been associated with African Americans and Hispanics since the 1970s. Hip hop culture gave them a voice, a way to express their frustrations with the system. It was also a way to channel out their culture and creativity through rap music and disc jockeying; and their art through graffiti. Hip hop – especially the music aspect has now become a globally recognized and accepted phenomenon proving to me a source of great wealth to the artistes.

Regardless of its growth, the origin of hip hop in the ghettos has not been forgotten, with artistes shooting music videos showing their so called ‘gangsta’ sides, and using lyrics that show the tough life. Due to this most people believe that despite the money these artistes get, they are uncultured and just from the ghetto with little or no education to boot. Well, quite a number of them did get a serious education- even went to college.

Rapper Common, previously known as Common Sense, graduated from Florida A&M University with a degree in Business Administration. He however does not fit the usual ‘stereotype’ of a rapper. Common is always calm and collected, his lyrics and diction showing his education level.

Popular rapper and actor Ludacris studied Music Management at Georgia State University where he graduated Summa Cum Laude. With his credentials to back him up, he successfully co-founded a record label (Disturbing the peace).

The real shocker was old school legend Flavor Flav, who now stars in his reality show (The flavor of love). Flav graduated from Adelphi University back in the 1980s although the details as to what he specialized in are scarce. Some rappers have even graduated TWICE! David Banner is a fine example of this. He has a bachelor’s degree in business and Master of Arts degree in teaching.

Most of the time, people go into the music business possessing only the talent, which is arguably the most important factor.
