If you mean the track listed under your name then go to Settings, Appearance and click this toggle. Assuming your on Damus because that’s the only app I know that has that feature.

you are correct, and yes, I found that setting and toggled it. It was a little bit of a jarring thing to see the enemy represented on my post. Lol.

It’s part of your user profile and not the post so it will change to whatever you listened to last.

Got it. I just don’t want it to point to Spotify, so I’ll change that.
