Username Change Assistance Needed on SongPop2

I hope you're doing well. I need your help with something. Regrettably, I accidentally used "villa movers" instead of "methewalvin" as my username on SongPop2, and I'm eager to correct this mistake. If anyone has any guidance on how to change usernames on SongPop2, I would greatly appreciate your advice and assistance.

Thank you in advance!

Best regards,
