Soulja Boy scored a viral No. 1 hit in 2007 with “Crank That (Soulja Boy)” thanks to his internet savvy, creating a blueprint that artists still follow today. After self-producing the song in 10 minutes with Fruity Loops, he used MySpace, Soundclick, and YouTube to promote the track. To get even more ears on “Crank That,” he uploaded it under the names of popular songs on illegal downloading services like Limewire.
