don't get music from streaming services because it's too low quality. instead hunt for FLAC format. it's lossless.

i pay for spotify premium (yes i hate ads THAT much) and when i download songs with it for playing offline there's a weird high gate cutoff which i can clearly notice and sounds like a dogwhistle to me. pretty sure it's the encryption rather than the sound quality tho. don't go that option - it removes too much of the shape of the music, fuzzes out too many subtle details.

if you're willing to pay for it, bandcamp.
