I know this is probably out there somewhere already, but I find it quite frustrating that I was assigned a "username" of lots of numbers when my account was created. It makes it hard for people to find me, as I can't remember my username, let alone try to get them to. Can we please make it an option to change our username? Even if there is a once-a-year change or something...that would be such a helpful thing!

Thanks for coming to the Community, and adding your vote to this idea.
Your username is designed to identify you on Spotify, so it can’t change.
However, you can now add or change your display name on mobile!
A display name replaces the username where it shows on your profile, app, playlists, and Friend Activity.
There's more on this here.
