no thoughts, head empty || nintendo music [niche & obscure edition] 

I made this list with a primary focus on Nintendo games (and soundtracks) you've likely never heard music from before*; that was the original intent at least. Keep an open mind (or a head empty brain) and you'll find some fresh favorites!
(*Note: I intentionally included a small number of songs that don't fit the category of "niche & obscure" to better help with the flow of the compilation.)
(Extra note: Utacchi is not a Nintendo game, but it sounds very Nintendo if you know what I mean, so I added it as a bonus.)
