I want to avoid over-headlining data.

So in my playlist, I will list the songs as text, rather than as headlines.
The problem is, I'd like to tag, in the following example, "(8) Beata
Viscera"
as my favorite composition in the Hilliard Ensemble performance.

** Classical
*** Pérotin

Dame school of polyphony and the ars antiqua style.
