I added Mike Love’s Unleash the Love album to the database when it was released, and I am now noticing that only 10 of the 25 tracks are showing up on his last.fm page. https://www.last.fm/music/Mike+Love/Unleash+The+Love This was the first and only time I’ve added anything to the database, so I’m sure it needs some cleaning up anyway, but I can’t figure out what the issue is. https://musicbrainz.org/release/2d374c4f-cad6-40dc-95ae-582d091a98fe
As far as I know last.fm is about “scrobbling”. That means that someone has to play those tracks and submit them as played to last.fm. The album is relatively new and has not so much listeners so far.
