Or I could get a mod tracker and some files from ftp://ftp.modland.com/pub/playlists/ and I would have the ability in a few 100 MB to make the type of music I enjoy (It would take 150GB to get every sample of every sound used in the entire world)

Hit up https://www.pouet.net/prodlist.php if you want a bunch of awesome demos ranging from 32 bytes all the way up to 32KB per

unxz.c is 60KB of code and everything you need to build it from source (with literally nothing but hex) only takes up 1.4MB of space https://github.com/oriansj/stage0-posix/
