Hi,
I would like to display the albumartist tag when browsing my library (in addition to the artist tag) and on the /playback page.
This would be really useful for classical music lovers, who frequently have multiple versions of a same piece. For example, if I’d want to listen to the Glenn Gould version of the Goldberg Variations, I would click on “Johann Sebastian Bach” on the artist page , and then, on the album “Goldberg Variations ($albumartist)” (the “($albumartist)” part would display only if filled). The Same thing on the /playback page: while I’m listening to my favorite concerto of Chopin, I would certainly enjoy being able to check the albumartist from this page.
I tried to take a look in /volumio/http but did not find the file(s) to modify… 
Anyway, volumio is an impressive piece of work, thank you so much!
Geoffrey.
