Roon is both incredibly great and excruciatingly poor

I agree to a degree. I’ve found and reported a number of headscratching issues with metadata. The Roon team (mostly @joel) always offers to fix issues upstream. I have not yet closed the loop to see if this actually works. It does seem like an insurmountable problem if Rovi doesn’t hire people that give a damn.

Do you have a sense for a the scale of the problem and how much of it is bad metadata vs Roon mismatching? If I had to guess, I’d say maybe 2-3% of my albums have serious issues so far. My collection is mostly Jazz, R&B and some Rock.
