Yeah, I did the same math, but I guess I didn't expect the cache files during streaming option to pull down the whole damn track before I can even skip. I like the idea of caching the whole file in case I hit spotty reception while playing, but it'd be nice if it was more intelligent about only getting the first 30s or so until it knows you're not skipping the track.

Alternately, they could use a recommendation algorithm that doesn't suck.
