...and the soundtrack to Read Or Dream the TV series...
This made me smile.
My GM had a huge library of lots of genres and he pretty much dug something out whenever it was appropriate. Man had a memory and a damn half. I'd suggest some of Frank Klepacki's work for Westwood, it's all pretty damn sweet. In fact, Unreal Tournament 2004 also has a pretty decent selection so long as you're looking for action music, you can fit a lot of variation in there.
For Anime OSTs: Paranoia Agent, Lain, Ergo Proxy, Baccano, Kara no Kyoukai (Garden of Sinners) might all contain stuff of use for Shadowrun. Depends on your campaign and the tastes of your players. Given that you use the Read or Dream OST I'd suggest looking at Baccano if you're slightly more Pink Mohawk than ROD, or Ergo Proxy if you're more Black.
