To start with 2010's music, some hip-hop. Oxmo Puccino and Booba were singing together in the underground crew Time Bomb back in the 90's. Now they are both very famous but as you can see, their styles have nothing in common.
Oxmo Puccino - Quitte Moi (leave me)
Booba - Foetus
And an other track of a good French rap album of 2010: Rocé - Si peu comprennent ('l'être humain et le réverbère)
