Listening to MIDI again?
I know it's quite a creepy hobby for me...
Anyway, if you still DARE to listen ot midi files, you MAY want to increase you listening experience.
Last time i suggested you Timidity player.
A good freeware but with some big limitations.

Right now I'm using SynthFont instead...a complete MIDI player based on soundfonts (sf2, dls) with editor capability, VST instuments and effects support and a lot of good features!
