I use Deemix/Deemon to track hundreds of artists and automatically grab new releases in FLAC from Deezer. It's slightly manual compared to my *arr stack with its Discord bot, but just a quick copy/paste from Discord/etc into a command.
Personally I have a Deezer Hi-Fi sub to get the flac's, not sure if their API is still wide open for MP3s or not. It used to be open for anything without a paid account.
