Backstreet's A.J. McLean is taking a break from the studio where he, Nick, Kevin, Brian and Howie are busily working on the group's follow-up to their smash-hit "Millennium".

A.J. paid a surprise visit to MTV's "Total Request Live" on Monday where he told revealed a few details about Backstreet's new songs to host Carson Daly.

A.J. said that the new album will be a mix of rock, R & B, hip-hop and a little bit of country. He also said that Howie is working with Babyface on a few new songs and that Nick will be playing the drums on some songs and Kevin will be playing the piano.
