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 Von 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 Du can look it up if u want 2. It's Lez Be Friends Von The Midnight Beast. Sorry this probally is not what ur looking for. :)
A few songs that come to mind are "Jesus" Von Betty and "Lick It" Von God-des and She, they are lesbian based groups. Du can go on Youtube and find these songs and Mehr songs Von these groups.
