Best Pay Music Download Service?
 

Assuming one wants to pay for their downloads to acquire them legally, what service does the best job and has the biggest catalog of music?

I don't use it personally but you might want to check out the new Napster store, which just opened this week and boasts one of the largest catalogs (6,000,000 tracks) available.

I use both Rhapsody and Zune. Rhapsody has worked well for me for the past 5 or 6 years now. I swear by it, because I can find almost anything I want there. Zune isn't all that great, but it's better than it was when they started.
