ProstoPleer! Russian website with direct mp3 downloads and uploads, playlist creation and sharing, just like the old GrooveShark. I was lucky that I made a backup of all my playlists 2 months before it happened.

Either Soulseek (Which still manages to be my one-stop shop for this kind of thing) or forums, but you’d have to find an active forum related to that niche. For example there’s Squidboard for game and anime soundtracks

Guess I will just use waifu2x then, thanks

Always worked for me, high res and all… The issue is only with Shutterstock, alamy etc are still working fine
