The snippets can just be a couple lines, a verse, and/or the chorus (like you can take the ending half of a verse and the beginning of the chorus). Also, you don't need to do all the snippets, you can just pick one from each set.

Preferably someone with a higher singing range (music shall be adjusted to accompany the correct pitch).

Rampion does her best to be optimistic and sweet, though it seems she secretly has a bratty and manipulative side to her. She's very curious and adventurous and so she wishes to see the world, though she was told that she was born cursed and thus can never even look outside. 

Rampion loved Gothel like her own mother, though she somehow figured out the truth of her adoption long ago. She also suspects that her curse was laid upon her by Gothel in attempts to prevent her from leaving. 

On top of believing Lindwurm capable of lifting her curse, she takes interest in the man out of attraction as well.

I tend to imagine her with a higher range and a sweeter and sometimes softer voice, though she can get really energetic and passionate.
