If anyone knows of a good music app with a sleep timer, please let me know. I need one so I can listen to some old audiobooks:
I normally buy audiobooks via Audible, whose app includes a sleep timer. Recently, I had to buy some older audiobooks on CD because they're so old they're not available as digital files. I ripped those CDs and now they're on my iDevices as music files, but the native music app lacks a sleep timer.
