Ok. There’s wrong meta data in Roon, e.g. wrong genre for an album (is Zoë Keatings “Into The Trees” really “Easy Listening”?). We are all aware.
Every time I see something like this (every other day), my urge is to correct or at least report it somewhere. I just don’t know where is the right place. And if it makes a difference at all. I searched for an answer here, but got swamped by the hundreds of singular reports that seem all to lead nowhere.
It depends a bit on what you consider to be wrong metadata. Genre assignments can be tricky. But a good place to start would be #support:metadata-issues.
If metadata originated from musicbrainz and musicbrainz being a community effort you could try to correct it yourself. Editing in musicbrainz requires some reading (style guidelines and such) and getting used to.
I’ve read that allmusic has a feedback channel you could use. Never done it myself.
