These are just different search engines – in Roon, you’re searching our metadata even in TIDAL, so it’s not using their search at all.
I agree we could be doing better here. I’m going to open a ticket and we’ll see if there are improvements to be made the next time we’re working on search. I don’t have a timeline for when that work will happen, but @joel and I will definitely take a look.
Thanks for the report, and the screenshots – was glad to see you weren’t actually searching for Marley Mark
