"You are the music in me" and "You're the music to me" in general have the same meaning. Both of these phrases convey that another person ("you") brings someone ("me") joy and happiness, like how music can bring someone joy and happiness. Because the phrase "You are the music in me" is from a song, the meaning of this phrase is up to interpretation.
