[Feature]: Support for Album & Track comments

[zeroquinc]

I have already checked through the existing feature requests and found no duplicates

• [x] Yes

Is this a server-specific feature?

Navidrome

What do you want to be added?

Navidrome WebUI has support for the %musicbrainz_albumcomment% tag. Could this be added to Feishin as well?

Same applies to the %subtitle% tag.

Much appreciated!!
