Thanks a lot for the answer. This looks interesting, I'll give it a try.
However, I was asking if it is possible to have the text as the title of
the live. For example, my live stream is currently named "Radio Dani (Live
24/7)", and I'd like to know if I can change the title dinamically to
"Radio Dani | Artist - Title" or something similar. :)

P.S. I'll send a link to the stream when I set it up with the filter you
mentioned. :)
