eMusic, the music service that has given Apple’s iTunes the most competition in the song-download arena will now offer audiobooks in mp3 format, too.

The biggest selling point for eMusic is also its biggest point of controversy: the site uses the MP3 format, which works on any digital player but lacks digital rights management technology, that protects copyrighted material from unlimited duplication.

This should provide some really interesting competition between iTunes, eMusic and Audible.
