I finally got my MP3 player up and working--whee! I went out to tuck the chickens in this pm listening to an obscure little song by The Eels called "I Like Birds"

This player came w/ an online music service free trial

--but it seems that all the music this service offers is indie, live versions, karaoke versions, etc, but not the original artists of the songs. Not what I want at all.
So my question is: is there a particular online music service/subscription that you like, and how much does it cost? Or are they all pretty much the same?
thanks, robyn
