I would prefer that all of the following were released on SACD and BR.
KMFDM - Their entire discography would be fantastic in surround, assuming they do not use the horrendous remasters of their back catalog. Distortion due to shredding and straight up clipping along with excessive compression and limiting which affects all their recent releases as well. -Chris Shepard did many of the pre-2000 mixes and have excellent dynamics and SQ, would be great if he was contracted to do such a feat.
Enya - Her entire catalog would be phenomenal in 5.1 but they would have to improve the mixes for the more contemporary releases, assuming the masters are the same, once again, compressed and clipped versions currently available.
Dead Can Dance - Also their entire catalog but not the 'modern' remasters, far less dynamic, such a shame since the originals sound fantastic.
The Chemical Brothers - Hanna soundtrack offered in 5.1 would be a lot of fun. Especially if they let things breath a bit more in regards of dynamics and not use the awful CD as a reference. What is heard in the film would be good enough for me. Everything sounds shrill, flat, and lifeless due to limiting, compression, and clipping on the CD.
Leftfield - Leftism is really a great album with nice dynamics and excellent SQ.
The Orb - U.F.Orb and The Orb's Adventures Beyond The Ultraworld are both interesting Pink Floyd -esque electronic albums. Again not to use the loud and flat remaster versions as the source.
Star Wars - All the soundtracks but especially the originals.
Politics is like a corral, no matter where you are you'll always be shovelling it.
