There is also https://hypem.com/, which focuses on music posted by blogs but is otherwise fairly similar. It helped me discover a lot of cool music back in the day :) Nowadays Spotify's music discovery algorithm is often "good enough", though.

Similarly there was We Are Hunted (https://en.m.wikipedia.org/wiki/We_Are_Hunted), before they got acquired by Twitter
