A couple months back I plugged a downloadable program that recorded sounds right off of your computer. I used it to record songs from YouTube or other sites. Sadly, the quality wasn't the best most of the time. I found a website that makes it much easier, much faster, and allows for better quality downloads. All you have to do is copy and paste the videos URL.
And now, Blessthefall's "Hey Baby, Here's That Song You Wanted"
