The only downside is that while Rush is great, MIDI Rush is not

Au contraire. You haven't seen Midi-Town Dreams yet.

Here is a proper MIDI file of that same song (Red Barchetta). The stuff they've collected there at that site is pretty amazing. The people they've got sequencing those songs are pretty darn amazing. One of the guys, GianFranco Fiocco, is a quadrapalegic and does everything with a mouthstick, it's absolutely amazing. By the way, that MIDI file of Red Barchetta that I linked is one of his.
