MP3.com backs Morissette and Amos

Music upstart MP3.Com is sponsoring a summer concert tour featuring Alanis Morissette and Tori Amos, a sign of growing acceptance by the recording industry of Internet audio sales. "The potential here is enormous. We've got to seize the opportunity," said Michael Robertson founder of MP3.Com, which takes its name from the technology that allows Web surfers to download CD-quality music.

Tuesday's deal won't allow fans to download songs by Morissette and Amos. It will use a different technology that allows for listening only. The site will be linked to one operated by Best Buy, a retailer and co-sponsor, where fans can buy CDs by mail.
