I didn't listen to anything particularly special this time, but I've been listening to Famitracker and YM2612 covers lately.
Here are my few favorite Famitracker covers by VinylCheese. His work is honestly one of the best I've seen listened to when it comes to Famitracker songs.
Amphobius alsh has some good stuff, especially on his YM2612 covers. Here are my couple of favorites covers from his work.
EDIT: I had to replace Amphobius' Green Grove Act 1 cover with the ActRaiser - Fillmore remix, as the it was was suddenly gone from SoundCloud. :/ If anyone could find his cover, that would be great and please let me know about it.
EDIT 2: I contracted Amphobius about this situation and he said that nothing has been removed intentionally. His SoundCloud Pro expired on him for some reason, and he plans on renewing it on Monday when he has the money to do so.
