Quick question about youtube....

[Sweet & Tender Hooligan]

I know theres a topic dedicated to this but seeing as its the g spot i just thought i would confirm it in another thread....Is there any way you can download JUST THE AUDIO from a youtube clip? There is a whole lot of unreleased Oasis songs that i cant seem to get on limewire but are all on youtube. Is there anyway i can get the audio?
