Replacement pack for the included soundtrack. It's reportedly better
OK, so over time I've had some complaints about notes in certain songs being off. I can't tell, but I don't really know anything about music. Either way, Astrocreep let me use songs from his Mac-style music pack, which should be more accurate re-creations of vanilla Mac music than mine. Download this addon and replace all .ogg files with the ones provided here. Original readme and credits included.
