What it says on the tin, songs that are lgbt, have lgbt ties, have lgbt artists, etc, but aren't in your face about it.
"Aren't in your face" is hard for me, but: It's A Sin-Petshop Boys I'm Only Dancing-David Bowie everything by Dead Or Alive Do You Really Want to Hurt Me?-Culture Club
There's a number of Senses Fail songs or videos which seem to be about worry about sexuality, which I always wondered about at the time, but which seemed more obvious after the singer came out as queer in 2015. In particular, the song Irish Eyes seems to be about the fear of coming out. It used to resonate a lot with me when I was younger anyway.
