Just trying to figure out DCMA makes my head hurt, no matter what. It pretty much goes without saying that I know filesharing of copyrighted material is illegal in the U.S., and The Music from the Cube posts were most certainly in a bad position from that point of view.

Streaming the files is safer, legally speaking.

Like I said, all things being equal, I'd rather do downloads because there's minimal administration on my part to do that that. Using streaming actually requires a little bit more work.
