Show Music Information Not Working

[Twin2turbo]

I have Show music information turned on under always on display, but it is not working. What am I missing?

Hi there, I think "show music info" shows what song is playing in the background, abit like shazam.

Yes, that is correct. My phone is not showing song titles of music playing in the back ground.
