At the same price per download, Rhapsody is better for anything but the iPod. iTunes packages the music in the AAC format, or MPEG-4 Part 3. The Fuze will decode MP3, WMA (Windows Media), secure WMA, OGG Vorbis, FLAC, and Audible aa formats currently.
The Sansa Fuze has a secret weapon, in that it supports Rhapsody PFS natively. If authorized in the Rhapsody client, the Sansa will support Rhapsody Channels, providing many hours of automatically transferred music in the genres of your choice. Any songes that you like can be added to your device library with a single click of the scroll wheel, or the song can be tagged for purchase as an MP3 or WMA file.
Rhapsody is going over to the DRM-free MP3 format for purchased music, meaning that purchased tracks are free of DRM hassles. They’re yours, free of constraints, download limits, burn limits, unlike iTunes.
You can use iTunes with the Sansa if you convert the files to MP3 format first.
I prefer the Rhapsody To Go service, which offers unlimited access to the entire Real / Rhapsody library, to load any music desired. To find new music, download the entire track, instead of listening to a short sample. If you wish a permanent copy, it’s simple.
