I'm gonna viral for Amazon MP3 real quick.
It should be checked on the daily.
They sell a different album every day for $2. Sometimes it's a bit more, like $3 or $4. It's not always great, but a lot of the time it is. New stuff, too. I got the new Morissey for $2 the other day.
They also do 5 for $5 Fridays, where they put up 5 albums for $5 a piece.
My music collection has BALLOONED since I started using Amazon MP3. I buy like at least an album a week.
