Is there an efficient way to search for really obscure files?

I crawled it in mp3 a few days ago. Give me a shout if you want a magnet.

Any luck on SoulSeek?

Looks like the album is in Deezer: https://www.deezer.com/en/album/299636

You can use Deemix with a HiFi ARL or SlavArt's Divolt/Discord server to download in FLAC.

Couldn't determine subreddit. Try requesting with both the url (https://old.reddit.com/r/whatever) and title (/r/whatever).
