So, I've been stripping every single piece of art attached to 1.5e5 music files for the past 4 hours. wo/ the duplicates, there are 11055, ranging from 20x20 to 3000x3000, or from 4kb to 8mb, anyways. I'll do a max compression 7zip and split it enough to be uploadable, but compression is from 1.9 to 1.8, but that's fine, given I don't understand how to use compression correctly.
If you're on linux, use join to recreate the single file, and then extract;
on windows:
https://superuser.com/questions/240086/how-can-i-combine-two-files-on-windowsuse waifu2x-converter-cpp to enlarge the smaller ones wo/ losing too much quality, there are nonetheless a lot usable ones with just black borders, since most album art is a square, given cd cases..
in the last archive are my favorites only (of the ones i've reviewed at least)
I listen to metal, jazz, and variety of other shits, hope you find something usable
