Maybe if you use Winamp for music with the SPCAMP files you can do the spc stuff...
But if you have a high quality sound card (like more than 16-bit) or a wavetable synthesizer (like wingroove) the Midi music sounds fine...
I just think that the Graal 2001 world should have new music...I mean think of it this way...some people have been hearing the same music for over a year
That's bound to drive anyone crazy...
But in my opinion MIDI is fine...it's small and of a very high quality if you have a nice sound card...
