The Beach Boys wrote very spiritual songs! Look at those lyrics: "But I hit hard at the battle that's confronting me, yeah Knock down all the roadblocks a-stumbling me Throw off all the shackles that are binding me down Sew up the wounds of evolution And the now starts to get in my way So what if life's a revelation If the mind speaks of only today So real, the pain growing in my soul Of climbing up to reality's goal" https://www.youtube.com/watch?v=RmAqpRFGzRQ "Long promised road Flows to the source, gentle force, never ending, never ending" The production is also way ahead of their time. Long live to these guys!
