Soulja Boy: On the heels of his smash hit "Crank That," which was No. 1 for seven consecutive weeks, many have speculated as to whether or not Soulja Boy will turn out to be a one-hit wonder. Considering the success of this song was due in large part to his online marketing skills (the single was initially self-published on the Internet), it seems highly unlikely that the ambitious 17-year-old will let his career rest solely on the merits of a single song.
