How can I add or edit my profile photo?
At the moment it's not possible to add or edit the profile photo via Musixmatch.
The profile photo is related to your login connection.
If you are logged in with Google or Facebook, your profile photo will be the same that you're using on Google or Facebook.
If you are logged in via Musixmatch (you added personal email and password), your profile photo will be the first letter of your user name.
