I thought that Brittany was supposed to be singing "Everytime"?

I was also disappointed when I saw that it was Marley singing everytime. I don't hate her or anything I just dint think a new character should get a solo every episode. Anyway I think Brittany isn't singing it because she already has two solos so three solos would kinda be overkill. I know I didn't really answer your question. Sorry lol.
