Johnny B Goode... from Wikipedia...summing up why Johnny B Goode is the greatest song... The song's impact on the rock 'n' roll world is immeasurable. Virtually every guitarist learns to play it early and its riffs and memorable guitar licks show up in the recordings of many of them later in their careers. For example, legions of guitarists rubbed their fingers raw trying to duplicate the startlingly original note-bending sounds of the intro to "Johnny B. Goode," which expanded on the techniques of blues musicians who were still warming to electric guitars. Yet the Beach Boys' signature song, "Fun Fun Fun", recorded in 1964, begins with that intro, copied so effortlessly and flawlessly by the studio musician Glen Campbell that it generates not a bit of tension. Berry's style is a standard in every rock and roll guitarist's repertoire. This song, arguably, had much to do with the establishment of the guitar as the lead instrument in rock and roll, rather than the piano or the tenor saxophone, both of which had been in the running since the emergence of the genre.
