I found all of these MIDIs at The Unofficial Ice Wars Page. What are MIDIs, you ask? They're basically synthesized versions of real songs which can sound cheesy at times, but are also way smaller in size than, say, mp3s.

Adagio by Bach (Music from) Apollo 13 Bring Him Home from Les Miserables (Music from) Mission Impossible (Music from) Schindler's List Here Comes the Sun from the 95-96 SOI finale Touch Me by the Doors (yeah! This one RULES! ^_^) (Music from) The Untouchables Why God Why from Miss Saigon
