Google Search: “dark side of the moon” “wizard of oz”
Almost all the song transitions match up with scene transitions, and most of the lyrics of Dark Side of the Moon can be seen to resonate with simultaneous things happening in The Wizard of Oz movie as well in one way or another. Although you have similar bursts of synchronistic energy in other synchs, none appear nearly this sustained or consistent; “Dark Side of the Rainbow” seems unique in this way.

I had heard of this rumor a few weeks ago for the first time, and am amazed to see how much there is to it.
