There's so many. Lots that flew under the radar which I consider classic.

lmao I own the MF Doom album with his mask on the front and can safely say ive only listened to it once, not my kinda thing tbh

i even own some MF fan tape about some Gingerbread Man or some shit lol the cover art is cool though, its like a concept album? the rappers name is MF something
