Did you mean "DO NOT WANT!"?
Spotify isn't an online music store; it started out as a music streaming service. They are actually doing very well, I've been using Spotify for over a year now and can't even imagine going back to anything else. The Spotify client allows me to purchase mp3's, manage my local library which I ripped from my CD's, and gives me a mind bogglingly huge array of music ready to sream at any time.
I strongly recommend you give it a try. Dont listen to the naysayers; people who complain about the recent restrictions on free accounts should really consider that a subscription which grants [b]unlimited[/b] access costs $5/month.
