Quote from Wikipedia:
"Many believe that this song (Let It Bleed) was a take on the Beatles' album Let It Be. The titles are very similar, and there was a running history of the Stones and the Beatles tweaking each other. The Stone's Let It Bleed was released months before Let it Be, but it should be noted that most of the songs from Let it Be had been recorded earlier than most of the songs in Let It Bleed, and was a known project."
