Music Monday! (Day 1 part 2)

OBS crashed, so here we are again.

For our very first "Music Monday", I'm playing one of the more well known rhythm games, involving a character who almost everyone over the age of 12 has likely heard the name of at least once. Singer of songs like "Rolling Girl", "Melt", and "Romeo and Cinderella".

I'm still not sure if her hair is blue, green, or teal, though.
