For those of you who have never heard of Sabi before, she is an up-and-coming rapper who has been featured on songs by Britney Spears, 3OH!3 and the New Boyz.  She is gearing up to release her first album later this year, and here we have the first single 'Wild Heart'.  I really thought that her rap on Britney's '(Drop Dead) Beautiful' was very amateurish, but with this she is taking the more Nicki Minaj route and offering us a good vocal performance.  Surprisingly, she actually has a really great voice.  What I also loved about this was the huge dubstep influence.  It reminded me a lot of Britney's 'Inside Out', but with an even harder and grimier beat.  If Sabi continues making amazing music like this I think that she will go very far in the music industry.  This is a must hear song.
