Music Transformer (was DRM Dumpster) is the automatic way to convert DRM tracks from your iTunes music library to standard music files. Simply set up your Mac, launch Music Transformer, click the Dump DRM button, insert a single CD-RW and the process runs automatically and unattended.
Music Transformer uses a CD-RW and iTunes itself to convert all of the DRM music files in your Library (or in a user selectable play list) to standard music files (MP3, AAC, Apple Lossless, AIFF, WAV) that you can use with any music player. Using a standard CD-RW ensures maximum compatibility because Music Transformer does not need to install any third party driver software - and that is a good thing.
The published price is that of a one-year subscription.
