Well I know 1 song about lesbians. But I'm not sure if it is the type of song u r looking for. It's a song 由 one of my fav bands called The Midnight Beast.But the song kinda makes fun of lesbians, not in a horrible way. Any-ways I like the song and think its good, so 你 can look it up if u want 2. It's Lez Be 老友记 由 The Midnight Beast. Sorry this probally is not what ur looking for. :)
A few songs that come to mind are "Jesus" 由 Betty and "Lick It" 由 God-des and She, they are lesbian based groups. 你 can go on youtobe and find these songs and 更多 songs 由 these groups.
