Just had a look.
Sounds a bit dodgy to me... I clicked on a "buy" link, just to see what happened... You just get taken to a very simple page where you fill in your credit card details. No sign at all of any secure payments and what have you. No option for paypal...
And the cost of tracks! $25 and more, for a single track. Very strange.
And you don't seem to be able to visit an artist page as such... just search for music.
Licensing agreement is a bit suspect too.
