Thank you for your prompt response.

Hi churatan​ 

could you translate what the encircled message says ? What kind of music is your loud speaker playing ? You can't dance to all the music.

Thank you for your prompt reply.
The sentence in the upper left hand corner is “The music is playing but I can't dance”. On the bottom right, “Dance” is grayed out and “Music must be playing nearby to perform this action.” This is the case.

What kind music are you playing ? I gave this a short test and while I couldn't dance to classical music, it worked fine with S-pop for example.

I forgot to give you an important piece of information. At the time of the photo shoot in question, the music genre was jazz. I know you don't dance to classical music.

Jazz can't dance, can it? When I made it metal, I could dance.
Sorry for the trouble.
