Kohina is a pretty good internet radio stream with all kinds of chiptunes and old video/computer game music.

I'd post my Lain playlist as well, but it appears that the albums included were removed from mediafire. Oh well. If you can find them, it includes the OST, the
Cyberia Mix remix album, and
LPR-309 concept album. Good stuff, listened to it non-stop a few months ago.
Shpongle is a psytrance group that is actually good. Give all of their albums a shot as well.
Bruce Haack was psychedelic music before it became shit. Really bright guy, built his own analog synths. Shame he died so early in his career. Try
Electric Lucifer out for a spin.
Ochre is a musician that I'm starting to get into. Some guy with a masters in music theory making strange blends of orchestral and electronic music; if you've ever played Final Fantasy Tactics, a lot of his stuff reminds me of that style, but with crazy synths added. Good stuff.
If you haven't heard of the 8bitpeoples, you're in for a treat:

I better stop now before I post every album in my library.
