Despite all the talk of the Internet ruining music, it can provide wonderful opportunities for a young musician. Take Kid Cudi, for instance. His song, "Day 'N' Nite," became popular on MySpace, and that buzz led to an appearance on our list of MCs to Watch in 2009. His music has been featured in commercials, video games and television shows. He landed a guest spot on Kanye West's 808s & Heartbreak as well as a deal with West's record label, G.O.O.D Music — all this thanks to a series of tubes and wires.
