From London to Laurel Canyon, artists were creating all-time classic hits while redefining the possibilities of what popular music could sound like.
The established acts of the British Invasion were at the top of their game, including the Beatles, the Stones, the Kinks, the Who, Dusty Springfield, the Yardbirds, Spencer Davies, Manfred Mann, the Hollies and the Animals.
Across the ocean, California was exploding with the sounds of the Byrds, the Mamas and the Papas, the Monkees, Jefferson Airplane, Beach Boys, Buffalo Springfield, the Doors, and Love. This year also saw the emergence of the likes of Simon and Garfunkel, Jimi Hendrix, the Velvet Underground, and Frank Zappa.
Soul music was rarely better, with the Supremes, Four Tops, Otis Redding, Stevie Wonder, Temptations, Percy Sledge, Smokey Robinson, Marvin Gaye and Wilson Pickett all in the charts.
Dylan was at the height of his creative powers, and even Sinatra had a #1 song. Aretha Franklin was on the cusp of stardom, a young David Bowie was cutting his first records, and Elvis released a steady flow of songs. Rarely was so much music royalty active at the same time.
All this was happening against a backdrop of military, social and generational conflict - not to mention increasingly open drug experimentation - and this fact was reflected in many songs of the time.
So here are, day by day, 365 songs from that momentous year. Enjoy.
