Rocker Lenny Kravitz is the latest to jump on the peace train.

The singer recorded a new anti-war track called "We Want Peace" with Iraqi pop star Kadim Al Sahir last week, reports the BBC. The song was posted Tuesday for download on the Web site of Rock the Vote (rockthevote.org), a youth-oriented political organization.

R.E.M., meanwhile, has posted its own anti-war song -- "The Final Straw," which muses, "Now I don't believe and I never did that two wrongs make a right" -- on its Web site at www.remhq.com, Billboard reports. Liner notes from singer Michael Stipe read, "We are praying and hoping for the lives of all people involved, the troops, the Iraqi civilians, refugees, POWs, families of troops, the innocents -- that they are safe and OK. Safe home, all."

Kravitz and R.E.M. join a growing list of anti-war stars taking a musical stand, notes the BBC. The Beastie Boys, John Mellencamp and former Rage Against the Machine frontman Zack de la Rocha have all written and released anti-war songs on the Web recently, while British ex-Clash guitarist Mick Jones teamed up with former Generation X and Sigue Sigue Sputnik member Tony James to record "Why Do Men Fight?" -- Jones's first recording in a decade.

The musical action hasn't made all acts popular with either radio stations or the general public. The Texas-based Dixie Chicks, in particular, have faced a fierce backlash from their flag-waving fan base after lead singer Natalie Maines made a remark disparaging President Bush at a London concert two weeks ago. She has since apologized for the comment.
