It’s an interesting problem. A good tag editor should help you see what’s actually going on.
I use MediaMonkey.
Or used to.
Though I hate to say it, I wonder if we will all abandon personal physical libraries of FLACs and WAVs. I have curated a collection of 4,000+ CDs into my Asset UPNP database on a Synology NAS. It took me 10 years to index everything satisfactorily. But since I subscribed to Qobuz I can get all those CDs at 24/96 instead of 16/44.1 and 70,000,000 others besides. So the NAS has not been turned on for weeks…
Yes! I went to Qobuz for the Sting duets album. Couldn’t find it; used my NAS instead. But that can be because of the indexing. Maybe in a separate list under ‘Sting and Various’?!
I still happily pay a premium for Qobuz for the joy of hearing so much stuff in 24/96
And there was I hoping you were a Naim type of chap Steve!
I take it you have not gone down the Roon route?
