Bdp24-Great post. I would like to add and simplify, regarding your comments. Dylan and the Beatles created/influenced the singer songwriter genre. The Kinks/Steppenwolf/Blue Cheer helped create "arena rock". The Who/The Doors/The Animals/Pink Floyd were responsible for the alternative/prog rock movement. Some of the bands especially The Who had an influence in all the mentioned genres. Springsteen had top level songwriting ability, then add the arena rock sound which created a very large fan base.
