but unlike Earthbound, where it doesn't seem like there was anything really blocking it from a Wii VC release, we know Sonic 3 has been off-limits to teams like M2 (for both the 3D Classics and Sega Ages lines) and D3T (where it was one of the few titles removed from the console port of their Steam collection). I'd throw in Taxman and Stealth's mobile remaster not being greenlit too but I guess one could come up with other explainations for that.
3&K hasn't been rereleased in a decade; do you have a better explaination to offer up if you don't think the music is the cause?
