Actually, my friend (in Norway) and I (in the USA) often listen to the same song at the same time because we want to share it with each other.

Most of the time that isn't happening, but when we want to, it'd be nice to have something to help with that.

Not that it's a huge hassle to hit 'play' on whatever youtube video he sends. The 10-20 seconds of lag aren't really that important.
