(1) My copy of Fly Like an Eagle is DTS. Yeah, that doesn't work. I deleted all of that, contemplated my tastes for a moment, and rebought the album through iTunes. Because I really like that album and I'm not fucking around with DTS and iTunes. People have been hoping Apple would deal with this for longer than my younger child has been alive. I am not optimistic.
(2) "Hand in Glove" doesn't sound any better on the CD. It is what it is.
ETA: DTS is a 5.1 surround sound encoding standard. Please don't ask me to explain it. You can search on DTS and CD or DTS and audio (quotes not needed) or DTS and iTunes if you want to see the things that made me so pessimistic about the idea that Apple would ever support DTS.
