U.K. anarchist collective/pop group Chumbawamba is expressing its pro-online file-sharing stance by taking on high-profile opponents of the practice in a new Internet-only song "Pass It Along" (MP3 Mix). The song, available as a free download from the band's Web site, samples Metallica, Eminem, Dr. Dre, the Beatles, and Madonna, without permission from any of the artists.

The song was recorded as a reaction to the argument of many artists and record labels that file sharing through such sites as Napster is "killing music."

"If [Metallica drummer Lars] Ulrich, Madonna, and Eminem had never sold any records and were worried about entering a poverty stricken old age, then their determination to stop their music being passed around would be understandable," Chumbawamba singer Dunstan Bruce said in a statement. "But what we're seeing is some of the richest pop stars in the world making the biggest stink about not being able to screw every last penny from their adoring fans."

Representatives for Madonna, Metallica, Dr. Dre, and Eminem did not immediately return calls for comment.

Chumbawamba's most recent Republic/Universal album "What You See Is What You Get," was released in April. The band's 1997 album, "Tubthumper," peaked at No. 3 on The Billboard 200, and spawned the hit title single, which peaked at No. 6 on The Billboard Hot 100.
