Oooh I will be downloading those myself!

You know, if you download the youtube vids with a program such as flashget or Download Helper for Firefox (works great) you can easily then get the audio with a FLV--> mp3 program, easy to find for free on downoad.com or the like. Or use Messer which records whatever comes through a soundcard.

People here might already know all that, but if anyone doesn't, it's a handy way to get audio.
