Okay, lemme get this straight:

Telephone element: Probably from a part of the background element from Jump (Major Lazer).

I had no idea of the hot air balloon, maybe an element from an unknown routine or a song that I forgot that it exists.

If you refer to the brown rectangular object as a slot machine, it is just a couch. I don't know which song it comes from.

The same can be said to the TV element though it features Side To Side ALT.

Pineapple balloon: Boys (Summertime Love) background element

Stop watch element: Possibly from Water Me Classic due to how simple it is.

I forgot where does the donut come from but I remember it involves with food.

A flying keyboard cat (rainbow animal #1) from Holding Out for a Hero and a horse (rainbow animal #2) from Gangnam Style.

Conclusion: You pretty much over-analyzed the elements. Good theories though. Too bad this is Ubisoft picture that we have, not a clue game made by Taylor Swift
