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 によって 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 あなた can look it up if u want 2. It's Lez Be フレンズ によって The Midnight Beast. Sorry this probally is not what ur looking for. :)
A few songs that come to mind are "Jesus" によって Betty and "Lick It" によって God-des and She, they are lesbian based groups. あなた can go on YouTube and find these songs and もっと見る songs によって these groups.
