Absolutely, though I rarely listen to music on my phone. That's just me, abd perhaps a bit age-related. But I "car dance and sing" all of the time. I sing in the grocery store to the music tgey play there. I've been known to dance down grocery store aisles many times. When manic I talk to myself in public. Actually, I'll sometimes talk out loud to myself in public even when "stable". I really don't care that much if I'm heard.
