[TOMT] cartoon piano episode

When I was younger I would watch a lot of random cartoons (idk when this cartoon was made but I watched it around 2013)

all I can remember about the episode:

there was some sort of piano thing going on and the main girl character was jealous of the boy character because he was better at piano than her.

She sits at the piano at some point and starts singing about the boy while playing music, I can’t remember his name but it went “[name] plays too much he really plays too much he plays when he’s nervous and when he’s calm” I can’t not for the life of me find the name of the piano music but it’s a popular beginner classical song.

There were pink and blue cupcakes and I think the girl steals the boys cupcake?

The tv show was in 2d from what I remember.

Any help is greatly appreciated! This has been stuck in my head for the past week and I haven’t been able to find anything on it. I honestly wanna make sure I didn’t have some crazy dream.
