Query: really nice

Well, I haven't actually used it with my exercise bike yet :) but I did play it for awhile to see what it was and I'm actually excited to exercise to it. The music is a little nutty - starts good but then goes to a slow classical piece (not the best to exercise to). So I'll probably mute it and listen to my Ipod. But the scenery was nice and there was a nice flow to the video. I'll probably get another in the series.
