A bit niche as it relies on musical composition knowledge. Also America by Simon & Garfunkel is a 6/8 time signature not 3/4.

I was super careful and chose only 3/4 songs- most of my original selections were indeed 6/8 but I googled all of the sheet music to check! The pop songs and Sound of music were hopefully distinguishable. The only knowledge needed to solve this grid was actually just telling the difference between the two Mary Poppins groups- no tech knowledge required- just an auditory imagination + familiarity with the songs- easy to tell that 4 are in waltz time. the hard part id thinking differently- about the music not the wording or facts about it. The specifics of the answer boxes were not required for points, just there for the sake of interest.

Is, not id- I've got a cold.

Really struggled with that one, very tricky :-)
