I registered as "500knives" but I have to log in with some gibberish name that read as "mmu0k6divz9f6bscmywduzcea"? I literally cannot login with my email or 500knives. So, what gives? I can't change my username, so...
Solved! Go to Solution.
It looks like you were able to add a display name to your account when signing up. Your username on your user profile will still show as 500knives, and any playlists made by you will show as made by 500knives too.
Hope this helps to clear things up. If you have any other questions, let me know.
