eMusic works on a subscription basis. I pay a monthly fee of around $20 USD and am able to download 90 tracks per month. The tracks can be from any album, from any genre, from any artist I choose, provided they have licensed their music to eMusic.
And now, for an addtional $10 USD per month, subscribers can choose an audiobook to download as well.
The selection is modest at the moment, although several well-known and popular authors are represented, as well as a good selection of the classics, and eMusic promises to add more authors and books on a regular basis.
I decided to try out my membership with William Gibson's Spook Country and Jonathan Lethem's You Don't Love Me Yet. The downloads were quick and easy, and, unlike, Audible, eMusic breaks each book into hundreds of tracks to make listening workable on any device. The files are good quality mp3s, just like the music, and will play on any music player.
$10 may seem like a lot for a single audiobook, but, considering that the same books often run $50 or $60 on CD, the price suddenly seems much more reasonable.
For someone like me – I have an hour long commute to work – this is a welcome addition to a service I already loved and I am looking forward to being able to get many, many books this way.
