I read the other day how "Andy, you're a star" by The Killers was apparently a queer song. That never occurred to me before and I bought the album when it came out. The song does imply "Andy" in the song is male, but there doesn't seem to be any indication of the sex of the narrator. That got me to thinking that we just generally assume the character is the same sex as the singer.
I was trying to rack my brain for songs where it was not the case that the singer and the narrator are the same sex (not including covers where a singer covers a song originally sung by a member of the opposite sex) and I could only think of two examples, both by Taylor Swift, and both on the same album: "Betty" and the second verse of "Epiphany."
There's no particular reason the character needs to be the same sex, every other type of artist regularly creates art from the perspective of someone not the same sex as them: screenwriters, authors, etc. So I wonder why it's become the default. What other songs are out there where the singer is singing from the perspective of a character of the opposite sex?
Edit: Thanks for all the suggestions! Looks like I have lots to check out.
