I’ve used this for several years. I miss when it was trivial to get scrobbling support on anything. Weirdly despite how portable players now have access to Wi-Fi & Bluetooth tethering, nothing support scrobbling out of the box. Last.fm even used to give good recommendations before it went downhill. You can say there is now value in trying to help ListenBrainz make a new recommendation algorithm with open data, but less folks have been using such platforms in the wake of leaving their data in the hands of Spotify & YouTube.
