So Im pretty sure you have heard this this track everywhere. And If you haven't I suggest you do. Its by an artist called "Kevin Rudolf". I guess he's a big guitar player in hip hop. He's done songs for Timbaland, David Banner, Will.i.Am and Lil Flip.
The song is sick. Lil wayne kills it. Couldnt find a pic by the way of this dude "Kevin Rudolf". So wayne is the best I do. Listen/Download
