I just sampled a bit of the streaming Atmos mix at low volume on my 5.1 system - I dunno if it's $200 good (is any surround mix?), but it sounds like SW has done a great job as per usual. The car sound effects in "Detroit Rock City" are all over the place as you'd expect, but then the main guitars come in from the rears! The call-and-response vocals in "Shout It Out Loud" are in the rears just as I'd hoped. There's very little in the back at the beginning of "Do You Love Me", but then the rears spring to life with guitars and backing vocals during the chorus.
