Today I learned that the Beatles' “Ob-La-Di, Ob-La-Da” is widely reviled. From the Wikipedia article:

“Ob-La-Di, Ob-La-Da” is often the subject of ridicule. In 2004, it was included in Blender magazine’s list titled “50 Worst Songs Ever!"[61] and was voted the worst song of all time in an online poll organised by Mars.[62] In 2012, the NME’s website editor, Luke Lewis, argued that the Beatles had recorded “a surprising amount of ropy old toss”, and singled out “Ob-La-Di, Ob-La-Da” as “the least convincing cod-reggae skanking this side of the QI theme tune”. That same year, Tom Rowley of The Daily Telegraph said the track was a “reasonable choice” for derision, following the result of the Mars poll, and it subsequently came second (behind “Revolution 9”) in the Telegraph’s poll to determine the worst Beatles song.

I always liked that song, and never thought of it as anything other than a light, fun song that is supposed to be—big shock here—light and fun. I’m more apt to be critical of art that takes itself too seriously.
