The Beatles had 'Sgt. Peppers', the Beach Boys had 'Smile' and the Rolling Stones had 'Their Satanic Majesties Request', a psychedelic-leaning album that is probably one of the most divisive projects of their career.

'2000 Man', ably covered by none other than Kiss on their 1979 record 'Dynasty', was a meld of what might have very well been two separate songs. Starting with an acoustic guitar accompanied by a simplistic drum beat in the first portion of the song, the group awkwardly enters a more 'rock n' roll' phase of the song, complimented by organ before returning the track to its acoustic beginnings. Of course, the Stones made it all work somehow, with a snotty, questioning vocal performance from Mick Jagger sealing the deal.
