I don't necessarily agree with the list at all. Although the no. 1 "Mr Blue Sky" is a pretty good choice.
There are no Gershwin or songs, so the list is already mostly crap right there. And what of Handel's "Happy happy" from Acid and Galatea?
The best sad songs are those that sound happy but which are tinged with melancholy. Burt Bacharach is the master of this.
The all-time happiest song that is a tale of woe is Gilbert Sullivan's one hit wonder: https://www.youtube.com/watch?v=D_P-v1BVQn8
When I was in college we would play music very loudly at swim practice. Mr. Blue sky was the first song on our morning practice tape. It’s perfect for warming up at 5:00 am on a cold winter’s day. The constant high tempo through a majority of the song was great to stretch out and get moving in the water. I would time my strokes to its beat. Lots of painful memories associated with that song. 😂
