I have been tagging tracks, albums and artists in various ways for some time now. As a reasonably senior (age) chap, i sometimes forget music titles I have tagged, so a useful may to view tagged music, would be by date added, which I find easier to recall.
Is this even possible?
As of now, there are no focus options for Tags, although that would be a great idea. Perhaps, put the request in Feature Requests?
You can use the IMPORTDATE tag to achieve exactly what you want. This can be the date you purchased a CD/download. You then need to go into Roon Settings - Library - Import settings and activate „use IMPORTDATE if present“.
This is what I do to be able to sort my library by the date I have purchased a CD / download.
