Question about Charles Manson songs

I’m wondering if any of Charles Manson songs can added. Although he was an absolutely horrible person don’t get me wrong, it goes to show he was a great songwriter, but can his songs not be added due to his actions?

I’m not a staff member, but I’m personally a big proponent of separating the art from the artist. If the art itself isn’t offensive, discriminatory or in any other way problematic, I don’t think it should be cancelled. The only exception might be if the artist is actively using the publicity to propagate their misanthropic ideology, but Charles Manson is dead so that is out of the question. I don’t know whether his songs have offensive lyrics, but I don’t think the crimes themselves justify cancelling his music.
