Song: Angels we have heard on high, as performed by Aretha Franklin. You don't want to miss this if you're into Christmas music -- and luckily, you won't have to miss it at all if you download this free holiday music sampler from iTunes. Did you hear that? FREE. And it has everyone from Aretha Franklin to Sarah McLaughlin to Musiq Soulchild to Weezer. But I think it's only free until December 15, so get it while it's hot!
