Can I Save Song Titles from a Live Stream?

[Chime Hart]

Hi All: Certainly when listening to a live stream in mpv, I see the song titles 
3lines up from the bottom. But if I record that stream to a file, I would also 
like seeing those titles. When I look for mp3tag here in SID, it lists 
ruby-mp3tag  but it doesn't tab-complete or show a man-page. While I tried 
searching in duckduckgo, my specific request didn't showup. Any suggestions 
please-and-thanks so much in advance. Shazam clients seem to only work with a 
single file.
