Trying to find a book i want to re-read

Hello all, im trying (and failing) to remember the name of a book I read when I was a teen (plz dont judge my memory is terrible for my teenage years). All I remember is that it was a fantasy novel and the main character ran away from her coven that she created and enrolled in a school. One specific thing i remember is a part where she listened to classical music on a stereo for the first time and cried. I think the title started with an 'I'. If anyone could help I'd be grateful 😭 i think this book came out late 2000s, early 2010s
