I use a combination of the 4chan /mu/ archive (https://archive.rebeccablacktech.com/mu/, just searching for "title + mega") and soulseek. Never left me wanting. Also if you download the music be sure to go to the artists shows to support them directly!
Yea it's true. Rate Your Music is a decent place to do discovery. Also even though 4chan is a cesspool the /mu/ board can be surprisingly great for finding out about obscure artists old and new
