On a more serious note, I think the music being used in-universe should not be given too much attention. I imagine Mirror, Mirror is the only song she actually sang in-universe of the ones that exist. She may be a singer, but she is probably not some well-known pop singer or even a professional singer. Her parents likely just indulge her habits to a ridiculous level so that she can do major concert performances on a whim. Of course, since the concert hall seems to belong to her family, that is pretty easy. That's probably true. Besides, her parents would never let her sing anything as rebellious as "From Shadows".
