Five best songs from the Summer of Love

5. The Beatles - "A Day in the Life"

All of the elements of the Summer of Love (festivals, LSD, mustaches) would probably still have happened if Sgt. Pepper had never existed -- but they would have been a lot less inspired. Released on the first day of June 1967, this tribute to sonic aesthetics inspired dozens of imitators and would firmly redirect the methods and styles of studio recording. "A Day in the Life" was the trippy, bi-polar mini-opera that closed the album, exhausting listeners with mind-bending lyrics and a backwards orchestra swirl that left your brain feeling as though it had been boiled in lemonade.
