If you want rockier songs go for Helter Skelter, I Want You(She's So Heavy) or Hey Bulldog. Or I Feel Fine(one of the earliest ever hard rock/metal songs, Kinks - You Really Got Me being the first). Try listening to The Long And Winding Road(first epic ever - first succesful anyway) or Norweigan Wood. Theyre both mad too.
