Username not changing in Music

Hello sofa143,

Thanks for reaching out to Apple Support Communities. We're happy to provide some assistance.

To do this, open the Music app on your iPhone, tap on Listen Now in the bottom left corner, tap your profile circle in the upper right of the Listen Now screen, tap on View Profile at the top, tap the Edit option on the next screen, then tap on Name and/or Username to change the Name and/or Username and edit as you need to. Then tap Done when you have made the changes you need to.

Cheers!

Hi sofa143,

Are you an Apple Music subscriber? You can verify at Settings > Tap your name > Subscriptions > Would be listed under "Active".

Also, was your device previously used with a different Apple ID? If so, then that is why you are seeing another name for the previously purchased music. Your device may also be Activation Locked, if the previous owner didn't follow these directions before you received the device: What to do before you sell, give away, or trade in your iPhone or iPad - Apple Support

Take care!
