I have music from some artists that have a frankly ridiculous amount of releases. I’ve gotten what I think are all of them, but over time and with new releases, I can’t be sure I haven’t missed an EP/Single/Etc. Is it possible to get a list of all releases of an artist, which I don’t have in my library?

There used to be such a feature in old version of MB.

But for now, until we can have some visual feedback of our collection, I used my userscript that tells me which release group, release, recording, artist are or are not in my collection(s):

Here I can see the albums I have, they have that purple highlight.
There is a very old HOW TO on that obsolete version page.

This ticket would bring that feature to MB:
