Subscription Music Programs/Sites

I am looking for a place to download unlimited music for a flat fee. I know Rhapsody, Napster, and Zune Marketplace all have subscription based downloads, but I dont know which one is best for me. I have looked through each and they all seem to have most of the music I want. However, I cant tell if some of the cds I would like are purchase only or not until I actually have a subscription. So, which of these three (or any others that you know of) has the biggest catalogue/database and least purchase only cds?

Thanks for your help.

Don’t they still have the 14 day free trials? Try one for two weeks, if you don’t like it cancel and try another…
