Is this a server-specific feature?

Not server-specific

What do you want to be added?

For tracks tagged ITUNESADVISORY=1 I would like to see a marker in the title of the song indicating the song is explicit. For tracks tagged ITUNESADVISORY=2 show a clean indicator in title of song.

Recommended marker is simply 🅴 for explicit and 🅲 for Clean.

An example would be:
🅲 You Oughta Know

Symfonium on Android is an example of a client that does this.

An accompanying setting to disable this feature would be preferred, set to disabled initially to preserve the current behavior.
