Cover art for Miss Y lyrics by Marina and the Diamonds

I think it means not being able to keep up with her competition in the music industry. Exactly the same with dancing, very relatable. You have to sit there and watch the kids who got more than you because your dance teacher prefers them and they are a better dancers because they got pushed and you didn't. Marina probably felt the same when she was doing just as well or even better, but was still not having the viral fame of which she wanted and deserved.
