In the world of modern R&B there's been an obvious shift towards the dancefloor, with cheesy synths being slathered all over the beats. What tends to happen when extra elements get added to songs that already have a lot going on, however, is that things get muddled and we end up with one big fat mess. Sometimes the song can technically still be defined as a mess but be so good it still works, but there are also times when all the elements seem to clash and you can't work out which bits a chorus and which bits the sound of your modem dying. Obviously, there are always exceptions to any rule and sometimes a mess of a song with no discernible chorus is still amazing (Girls Aloud's 'Biology' please stand up).

But, we digress. R&B messes. This is a hot mess that works brilliantly:

This is just a mess:

This leads us on to the new single by Estelle. Produced by dance titan David Guetta, it samples about three different songs, has no real chorus and for all its bells and whistles is just a bit of a, erm, mess really.

The less said about Karinall Offishall the better. He makes Flo'Rida seem like Nas.
