Best Places For 'Legal' Music Downloads ?

I have downloaded approximately 6-8 CD's (I only put about 20-22 songs on a CD) from CD Now. They provide free sampler full songs from a number of their artists. You have to spend some time looking for them. Tower Records probably does the same thing. As for music services, I like Rhapsody. It has the music variety that I want and just tons of music that I would not care for at all, but that's ok. Not everyone likes everything. Rhapsody also has a lot of "radio" channels and it even has a sort of free "radio" service. The free part has a very limited number of channels but one of the free channels is BLUES which is the type I really enjoy. Don't overlook the new Wal-Mart service. It is fairly new and is building its repertoire. The Wal-Mart site does not require a monthly fee, it just charges per download and at last look I believe it was 88 Cents a song.
