Naxos Music Library has both iPhone (iPod & iPad, too of course) and Android Applications available for download!
Copied from the Naxos Music Library Blog (you might want to bookmark it!!)
You access the content from your mobile device by setting up a 'playlist' account when you're logged in through the UWM system (either from on campus or standard off-campus logon).
You will be able to listen to personal, institutional, and Naxos-created playlists as well as browse and stream the full NML on the go from your app!
1. Visit the NML. If you are a member of an institution like a school, university, or public library, you can visit your institution’s unique webpage (ex. http://myschool.naxosmusiclibrary.com). Ask your librarian or contact us here at Naxos if you’re not sure how to get there.
2. Navigate to the Playlists tab and sign up for a Student/Member Playlist Account. You will receive a confirmation e-mail to the e-mail address you used to sign up. Click the link in the e-mail to confirm your account.
3. The login you created for your Student/Member Playlist Account will be your login for the app as well.
4. Any playlist in your personal folder or your institution’s folder will be available, in addition to all of our Naxos-created playlists. You can also browse and stream the full NML--from New Releases and Recent Additions to any old recording from any label--anytime, anywhere.
