>>126811003This has been true since Boomers. Rick only knows this because he was former professor and music producer. Rick himself wrote or ghost wrote a lot songs for the buttrock bands he produced, like Shinedown and Scott Stapp (but he also produced good song writers like Owen Beverly). Even most bands are the vision of one person in the group, like Jimmy Page doing 90% of the work in Led Zeppelin. Most musicians, even good ones, like Slash or Eddie Van Halen can only write their parts and are not capable of arranging or putting whole songs together. It's why each line-up of Van Halen sounds radically different despite only changing the singer, and why Velvet Revolver only worked due to Scott Weiland.
