New York - CBS-owned (NYSE: CBS) social music discovery service Last.fm said on Monday that the Dandy Warhols have joined its Artist Royalty Program, which allows artists not affiliated with a label or collecting agency to accrue on-demand and streaming radio royalties directly from Last.fm every time their music is played on the site. The band started its own label earlier this year to release its eighth album, "Earth to the Dandy Warhols." Last.fm said that its Artist Royalty Program now counts more than 200,000 participating artists.
