Any and all "good" Batman Soundtracks/Scores etc….

Thing is, I just recently got Arkham City, and what better way to enjoy that game than to get as many Batman songs for it as possible, right?

Particularly I want to track down any and all Batman Beyond songs, I have the first album, but I know that only covers Season 1. I have no idea about Season 2, Season 3, or Return of the Joker, Justice Leage Unlimited’s "Epilogue" or whatever.

I like Shirley Walker’s (R.I.P.) works too, and especially Danny Elfmann’s.

On a side note, I have Batman Forever’s "music inspired by the movie" (Method Man’s The Riddler), and the stuff from Prince (The Artist Formerly Known as Prince) for the 1980s Batman movie.

Can anyone help me complete my collection?
