Napster (NASDAQ: NAPS) -- the mother of all file-sharing services that in 10 years' time has found itself one among many digital-music services struggling for its very survival -- is hoping its new move will attract more users. Today, Napster CEO Chris Gorog said the company is shifting to MP3 downloads free of digital-rights-management software [subscription required], or DRM. The move is expected to occur sometime in the second quarter, but Napster has yet to finalize the arrangements with some of the four major music companies - Sony Corp. (NYSE: SNE), Warner Music Group, EMI Group and Vivendi SA's Universal Music Group. The final three on this list recently began selling MP3s on the download service available through Amazon.com (NASDAQ: AMZN). Sony has yet to report plans to sell its tracks as MP3s, but is reportedly expected to come forward soon.

Both albums "dropped" on September 11.
