Anyone used "napster to go" ?

[Unoriginalname]

Does anyone have any experience with napster to go? Do you think it's worth it?

It says on the web site that with the $14.95/month subscription, you can get an unlimited number of songs to play on your computer AND your supported MP3 player. I know that you can no longer play the songs on your computer if you cancel your membership but what about the songs on your MP3 player? Could I buy 1 month of subscription, load up my player with thousands of songs, and then cancel my subscription but still be able to listen to the songs through my MP3 player?
