Props, you two. You really handled this genre well. Whilst some may find it on the repetitive side, this is the sort of music which isn't supposed to end - it's used a lot as BGM in anime and digital comics.
I thought the length was spot on, though, to add to the "driftness" of the genre, I would have extended the fade out a good 15 seconds longer This is coming from a guy who isn't really fond of fade outs, but for this sort of music, I actually prefer them.
Also, the "MIDI-ish" choice of samples were perfect! I guess this mix gets a bit more critism than most others, since it's not often you get one of these types of music handed to you. Once again, superbly done. I always get a big grin on when I hear this song .. not to mention the little 'kick' back into the groove @ 2:15
