"The music likes me not" - "The music" is the grammatical subject, so the third-person singular conjugation "likes" is used. "Me", being the object form of the first-person pronoun, is the object of the sentence. It's comparable to how in Spanish, you'd say "Me gusta la música" and not "Yo gusto la música" - the person that does the liking is the grammatical object, and the thing that the person likes is the grammatical subject. Except, in English, unlike in Spanish, it used to be in free variation which things were the grammatical subject and object. You can even see how, in Old English, the person who liked was put in the dative case[0]. Translated into modern English, the lines would be: You don't like the music. You're wrong. I don't like the musician. Another verb this happened to was "to think." The word "methinks" is a archaism/holdover from when "think" had the meaning "to seem" and so "me thinks" came from Old English "mē thyncth," which had the first-person in the dative case.
