Add suffix in tag display

[Donuk]

If I may bend this thread a little. I think I know what the o/p wants to achieve.
My own personal wish is that I can insert "Composer: " in front of my composer tags as they scroll on my Linn streamer or show up in my control app.
So I see "Composer: Lennon~McCartney" instead of "Lennon~McCartney" which is of course in the metadata.
I am sure it is easy.
Apologies if this is totally irrelevant.
