**SPC music is emulated music and reflect the actual song far more accurately than midi or modular files usually do (though modular files can be just as good in some cases).
**The only musical file types that more accurately represent the music from the game would be types such as MP3 or WMA, which are usually burned directly from the soundtrack CD. These types of files are not offered at CTSite, but the soundtrack CD's can often be found on eBay for pretty fair prices.
