Let's get back to a couple of names that should illicit a little more participation, and are closer to the glam/metal sound. In their day, they were absolute heavy-weight lead singers. The Cult has certainly endured much better than GnR, but c'mon... Appetite for Destruction is (was?) the best selling debut album of all time... thanks in no small part to Axl's unique sound and delivery.
He's a douchebag now, but I'll take Axl based on the debut alone.
