Also known as "facets". Sometimes you might want to browse "year/album/artist" too (think Various Artists / compilation albums), instead of the more common "artist/year/album". Or even "artist/year/album" for the more prolific artists out there.

Progressively "drilling down" is super low-hanging fruit with regards to tag-based organization, it's seriously neglected.

Thanks, that's ... closer to what I have in mind.

I also agree that the lack of drill-down on tag-based organisation ... kills about 99.9996% of the value. It's sufficiently valuable that you'd expect this to be part of basic implementation libraries by now.
