I'm trying to figure out, in Egyptian Arabic, how a person would say "The type of music you listen to says a lot about who you are". Or similarly, "The types of books you read says a lot about your character..."
Here how I would say that:
الموسيقى (أو نوع الموسيقى) اللي انت بتسمعها بتعبر عنك
نوع الكتب اللي انت بتقراها بتعبر عن شخصيتك
If you focus on the phrase says a lot about I don't think translating it litterally is familiar but we can say:
نوع الكتب اللي بتقراها بتقول كتير كتير عن شخصيتك
