Oh, I love listening to soudtracks ! I do it ll the time ! Films (Inception, Avatar, Lord of the Rings, Oblivion...) or even anime (Naruto, One Piece,...) My favorite one are always from Hans Zimmer, his the best for that !
Weeeeell I love soundtracks. My favourite are: Hedwig's theme, Lord of the rings theme, Heart of courage, The battle song from The chronicles of Narnia and Schindler's list.
When I was younger, I used to listen anime soundtracks.
Now, I like the DC Animated Universe soundtracks (especially Batman The Animated Series of 1992), Chris Colorado (a French animated series) and The Lord of the rings. No, I'm not thinking about Howard Shore's compositions for Peter Jackson's movies, which are never the less quite good. I'm talking about Stephen Oliver's musics for the radio serials of 1981 from the BBC.
I quite like certain video games soundtracks. I can't play video games because of my blindness, but I can enjoy musics. I like for example Final Fantasy, Dragon Quest and Soul Calibure's music.
I'm a big fan of Hans Zimmer's. As my favorite, I'd say "Spectres in the Fog" from the movie The Last Samurai. Soundtrack and the scene perfectly match.
