Definitely a crazy song to play on a guitar with all those unusual chord changes. But, I can think of a few pop songs in mixed meter than are more challenging, musically.
Kashmir comes to mind immediately. I still don’t know what time signature is in that song. Drums are playing something with all others playing something else. Very hard song to play.
Pink Floyd’s Money is also in a strange meter.
I listened to Dark Side one memorable night on a Detroit radio station as soon as it was released. Probably WABX, WRIF. Was so intrigued, and it took me many listens to figure out why I couldn’t replicate the song in my head, I kept trying to add notes to fit it into 4/4.
