How vast is #SNESmusic?
Counting only the 1517 soundtracks presently ripped to SPC format (I haven't folded in the few in SNSF, and several games resist ripping altogether)...
There are 34,789 tracks among them. Some of these are just very short sound effect tracks, some are long loops of ambient sound, some are merely alternate versions or duplicates, but those probably don't account for more than a tiny fraction of the total playtime:
5wk 3d 14h 41m 48s.
This will take a while.
