Key changes have been used as a gimmick in songs as a way of trying to fool the listener that the artist is somehow musically savvy rather than creating interest in the piece. So a key change isn't always a sign of a good piece of music. It has to work and be necessary to the piece.

The overwhelming vast majority of current music has absolutely no staying power, is uninspired, lyrically lazy, copycat rather than influenced and repetitive beyond belief.

Every so often a really good song will come along but it is rarer and rarer because so much of a piece of music is focused on how the visual presentation will be.

All of the above is my opinion and your mileage may vary.

I heard a nice "new to me" piece of music last night, driving in the car with Mrs. Sooner and listening to the classical station. It was a fun, humorous little piece for violin but still, let's say not just anyone could play it.

And in fact someone was playing it. Playing it, indeed.

I said to Mrs. S, "That guy can play. Or girl, whichever, but that person can play."

"Dance of the Goblins", Antonio Bazzini, Op. 25, performed by Itzhak Perlman in Russia.

Back to the OP's point, I don't believe it has any key changes in it.
