The band is called Harkonen. I don’t know much about them except that they’re very, very heavy and that I like to scream along to them in the pickup when my voice is up to it.
The song title is: All This Time, I Thought Your Name Was Cool Dude
And the lyrics are: “All this time, I thought your name, was cool dude. But it wasn’t you.”
So very true about so many people, and no poetic beating around the bush to get to it. Music needs more songs like this.
