A couple comments, from previous posts:
1. The surround mixes used on the new disc are the same ones used on the old DTS disc.
2. Someone inquired about the remake of "De Doo Doo Doo." As far as I know, this one first surfaced on the DTS disc, and has never been available anywhere else (or in a standard stereo mix, for that matter). Basically, it's from the same sessions that produced the remake of "Don't Stand So Close to Me" in 1986. At the time when the group was assembling the original "Singles" collection, it was decided to remake a few of the songs. As it happens, they only completed two, before friction and tension within the band sent them scattering again. (And it didn't help much that Stuart Copeland had broken his leg and was unable to really participate much in the sessions. Notice that most of the drums on those two tracks are in fact drum machines.)
I still find the surround mixes of these tracks (either the DTS or the new SACD version) are some of the best out on the market. It's really too bad that they didn't go the extra mile and done surround mixes for all of the albums. And I'm genuinely miffed that they didn't bother to release hybrid versions of the albums (forcing people to essentially buy the albums twice if they want to listen to them virtually anywhere OTHER than on their home stereo system).
