I was into soundtracks for a few years and then lost interest for whatever reason. Favorites were Batman and Batman Returns, Waterworld, and Robin Hood: Prince of Thieves, despite the Bryan Adams song being on there too. :-(
The only thing close to recent that I bought was Lord of the Rings: FOTR.
Oh, and I don't have Rushmore, but I do have the DVD and the music is pretty darn good.
