Yohko Kano 0wnz never the less (Macross Pluss, Escaflowne, GITSSAC, ect. ect.).
Check out Ghost in the Shell: Stand Alone Complex - now that's some serious series, where each episode could stand on its own as a film.
Both Bubblegum Crisis, and the subsequent (and lot better realised) remake BGC 2040 Megatokyo had good soundtracks. The first is my favorite 80' j-rock with a sense of darkness that's otherwise very alien to the style (Try to grab a subbed version with the lyrics translated too - you'll quickly get want I mean. Who can come up with such a corny never the less fitting line for cyberpunk as "What is the world coming to with a Devil kissing an Agel?")
BGC 2040 had some good 90' rock music, and Priss Asagiri once again shines, though I don't now if the seiyun was a singer just like in the OVA.
(PS.: Avoid BGC - Crash like plague, some ppl wanted to grab some serious money, but they raped the story to cramp in as much showy non-sense as possible)
