At the part towards the end where Violet is making a copy of her song on her computer, she burns the song onto a CD. But the CD is upside down in the burner.
You both are wrong. If you look when Violet puts the c.d in the cast it shows the cd top where you write what is on the cd. So she did put the cd in wrong.
Actually, I have found that there are CD players and burners out there that you have to put the CD in up-side-down because the lens is above it and not below There is a possibility that she had one of those.
