Beach Boys, "Never Learn Not To Love" (1968)
The only entry on this list that was recorded before the murders. Since Charles Manson and Dennis Wilson met in early 1968, the drummer had introduced Manson to his friends and even set up a session to record a demo – which would be released in 1970 as Lie: The Love and Terror Cult – but no one was willing to give Manson a deal. Dennis did, however, manage to get one of his songs onto his band's 1969 album 20/20, which was a small coup for Manson. Though the song's lyrics about getting a girl to submit went largely untouched, they changed the original title, "Cease to Exist." Worse, Manson didn't even get a writing credit on the LP. Needless to say, he was not pleased.
