The second round of the Choose the Cover of Rolling Stone contest is under way. After hundreds of thousands of votes were cast online, the 16 acts vying for the cover of Rolling Stone – as well as an Atlantic Records contract – have been narrowed down to a group of eight. Those bands have since gone into the studio to record two songs each with top producers, and you can now download each of them by right-clicking on the track titles.

Voting for round two will end on April 14th, and the final four contestants will be announced at the end of the month. In the meantime, please check out all of the songs and vote for your favorites.
