Awesome, but this almost drained my macbook battery dry, or at least that's my suspicion. It was in a background tab, but I noticed the name of the playing song had changed, even though my volume was down. Chrome should have some way to prevent a background tab from playing music while the volume is down, and web designers shouldn't expect you to have it turned up! Shouldn't there be an HTML5 hardware API for that??
