I don't think you can run afoul of the RIAA. Check out this link for more details: http://www.museekster.com/allofmp3faq.htm

The music selection is hit and miss. It's not near as extensive as iTMS but it's about 20X cheaper and doesn't come with any technological restrictions (like Fairplay) on how it's used.

Your mileage may vary, but so far they've had around 50% of what I was looking for. Not good enough to keep my business at "normal" prices, but at their rates, I am willing to pick through their stuff.

The explorer program that they offer (mentioned above in alanw's post, works in the Windows environment only, so I haven't tried it out.

I am not sure if the artists recieve any royalties. If they do, it's not much, I'd guess. I don't feel bad about it though. If it's truly legal, and my research indicates that it is, hooray for me! Depeche Mode never thought twice about charging me crazy sums like $18.99 for a new release that had songs on it from previous releases. Now it's my chance to get music significantly cheaper.

I don't like the idea of stealing music -- but I don't mind using export law loopholes to get it on the cheap.

Just my two cents,
