So, if you've never played WISP before, this series from "Let's Play" walks you through the whole game in 4 videos. Very interesting if you've never seen it before:

The video inspired me to pull out WISP again, particularly to find the 9 minute "MAIN" track that they talked about at the end. With some guidance on the length of the track, I was finally able to rip it properly, which I had never been able to do before.
It turns out that it's a 9 minute mega-mix of Mo Move, Soopher, Ansum, and the wind chimes heard on Ess Gee. It's likely that Karl's vocal take is live (you can hear his mess-up in the beginning), and so it's possible that the whole track is a live mix by Rick.
Unfortunately, for disk space reasons I assume, the track is only mono and at a lower sample rate (which is why I couldn't find the correct ripping settings before). Here is the download link:
