Good idea Threehorn!
If anyone is interested, I have the full, uncompressed videos of the episodes with maximum sound quality, much better than the ones I've been releasing here (a 22 minute episode is over 1 GB:P)
If you're interested I could extract the songs out of these, as they're bound to be much higher-quality than the audio found in the compressed videos I've been posting.
I don't have the songs recorded from the episodes yet; I've just been too busy. But I could do it as soon as possible if you're interested. Until then, threehorn seems very willing to share his recordings!
