The iTunes Music Store is launching with a library of 200,000 tracks, with participation from all five of the major record labels. In addition, the store will list exclusive tracks from 20 artists, including Bob Dylan and U2.
The songs cost 99 cents each to download, with no subscription fee, and include the most liberal copying rights of any online service to date. Jobs has been an outspoken opponent of so-called digital rights management (DRM) in the past, arguing that limitations on digital music will undermine the market for legitimate content.
