Sometimes I forget what org-mode is built on...

It would be nice to keep things in the org-style (e.g., :favorite song: is
preferable to "<--- favorite song," just on rudimentary aesthetic grounds.

But what you suggested will do.

Tagging outside headlines doesn't really make sense in Org,
as all tagging-related features need the tag to be on the headline.

But you can still use... plain text + emacs power:


  (8) Beata Viscera <- My favorite song!

M-x occur RET favorite RET

HTH,
