Problem 54695. Spell musical triads

I can empathize, and I won't claim to be qualified to explain. For major chords I think of "sharp keys" and "flat keys" as listed on this page:

The circle of fifths shows the difference nicely. It also shows that the key of F# has six sharps and Gb has six flats. No wonder those are troublesome!

With such confusing notation, it's a wonder the music industry is as successful as it is.

I'm not an expert on popular music, but the current #1 song, As It Was by Harry Styles, has four chords: D Bm E A. See also David Bennett's video "26 Songs that Only Use Two Chords".

But the best is "How to Make an AC/DC Song in 30 Seconds": https://www.youtube.com/shorts/k3zCnTgdLG0

Gregg Moscovitch wrote, "When told that a critic had accused [AC/DC] of recording 10 albums that all sound the same, guitarist Angus Young quipped, 'He’s a liar. We’ve made *11* albums that all sound the same.'”
