Listen to MyTube
If you want to get an MP3 of a YouTube video, there’s an excellent service called Listen to YouTube that you can use to strip MP3s from videos. Being able to take a tune with you on your iPod or phonograph is pretty handy, especially when it’s “I’m On a Boat.”
For real, I made a boat mixlist made up of only that track. Andy Samburg, you tickle me.
