It doesn't need to have the same male/female roles. I think I'm just looking for songs involving polyamory (or multiamory/polyphilia for those who care about the root origins) that aren't about cheating. Or at least a song where a polyamorous relationship is suggested would be fine.
Are there any songs that have a similar theme to that of the song "Triad" by Jefferson Starship, Jefferson Airplane, or whatever they were calling themselves at the time?
I know this thread is old, but I had to respond: The Weakness in Me (I like the Melissa Etheridge version the best, but the Joan Armatrading version is much easier to find).
