I have 35 of them, but I'm still not convinced that '73 was the year for me!
I'm erring towards 1967, not because of the number of great albums that were released that year, but because of the influence just a few releases (albums and singles) had.
Try this lot for size:
ALBUMS
The Beatles - 'Sgt. Pepper' and 'Magical Mystery Tour'
The Doors - 'The Doors' and 'Strange Days'
Jimi Hendrix Experience - 'Are You Experienced?' and 'Axis: Bold As Love'
The Velvet Underground - 'The Velvet Underground & Nico'
Jefferson Airplane - 'Surrealistic Pillow' and 'After Bathing at Baxter's'
Pink Floyd - 'Piper at the Gates of Dawn'
Love - 'Forever Changes'
Cream - 'Disraeli Gears'
The Byrds - 'Younger Than Yesterday'
The Rolling Stones - 'Their Satanic Majesties Request'
The Nice - 'The Thoughts of Emerlist Davjack'
FIVE BEST SELLING SINGLES
Procol Harum - 'A Whiter Shade of Pale'
The Monkees -'I'm a Believer'
The Beatles - 'All You Need Is Love' and 'Penny Lane / Strawberry Fields Forever'
The Doors - 'Light My Fire'
OTHER NOTABLE SINGLES
Aretha Franklin - 'Respect'
Bobby Gentry - 'Ode to Billy Joe'
Van Morrison - 'Brown Eyed Girl'
Dionne Warwick - 'I Say a Little Prayer'

The Moody Blues - 'Nights in White Satin'
1967 was also the year BBC Radio 1 first broadcast.
