Ran across this
website and I must say that I love it. You can type in practically any song you want and up it comes and will play on your pc via their browser embedded music player. I typed in 1234 looking for Feist and received about 20 hits including live versions, etc... Not sure of the legality, but it was published in PC Magazine not too long ago and provides the opportunity to purcahse the song, but that is done via a simple google search. The quality is very good. A simple loop back recorder on your PC and you could easily fill your hard drive. Merely an observation, not a suggestion.
