Wipe Out from Still Cruisin (my pick for worst Beach boys song) and Summer Of Love (you can add Smart Girl from Brian Wilson solo career) are so exceptionally bad that it is entertaining to listen to. they are the music equivalent of so bad it’s good movies like The Room. They are kind of essential to listen to from appreciate the other extreme in quality spectrum

Although i do maintain that Summer Of Love Mike love has some degree of self-awareness regarding the humour of it.
