It definitely looks like the song skipping problem has been greatly controlled, and it is quite possible that it is gone completely (I have yet to experience a skip so far).

I can also confirm that playback is extremely stable even while switching between Wi-fi and cellular data, and while traveling in a car through various gradations in cellular network quality (from EDGE to HSDPA). Manipulating the controls (skip, play/stop, thumbs up, etc) seems much more reliable even when used on a cellular network.

I'm liking the flashy gui also.
