Sorry, but it just keeps getting worse. Looks like Roon acquired access to high-res pictures from a low quality company, with cheap garbage coverart like the Not Now reissue junk label:
I’ll stop here, but it’s really all over the place. Pure horror to look at what no longer feels like my own collection — which always was one of the reasons I don’t stream. I want to control my own music and do not want anyone to change it. I’ve spent months editing my collection in Roon, and in a blink Roon completely messes it up.
An update from the Roon team on what they are doing about it and with what priority would be nice — and most reasonable to ask and expect, I think.
