Watch out - I too am trying to buy a player for Rhapsody to go - to play the files without purchasing them (like renting them, as someone on this forum mentioned).
There are three different levels of Compatibility - basic, download and subscription.
The Sansa will NOT play Rhapsody downloaded files unless YOU HAVE PURCHASED THEM, so it is really not fully compatible with Rhapsody to go. You probably want a device which is listed as "subscription", not just "download".
There are not too many and the Sansa is not one of them -
Here is the information from the Rhapsody website:
Different types of devices are divided into three levels of compatibility -
Basic: Plays simple MP3, WMA, AAC etc.
Download: Plays all of the above, PLUS secure music purchased from Rhapsody
Subscription: Plays all of the above, PLUS subscription downloads from Rhapsody To Go
"subscription" level devices are Iriver H10, 120, 320, 340 - then two Creative - Zen Micro and Zen Portable Media. Also, the Rio Carbons and a few others. Also listed as "subscription" are the Samsung 920 and 820. Does anyone else use one of those devices without using Napster, but using Rhapsody? I was thinking about picking one of those up because they are inexpensive, but I was worried that I would have to use Napster to do anything, and I want nothing to do with Napster at all, since I already pay a lot for Rhapsody, for myself and family. Rhapsody is the best for playing music online and finding lots of music to play, and we are all used to it.
