I analyzed the chords to 1300 popular songs for patterns. This is what I found.

Hmm, one could also use a Markov chain on those 1300 chord progressions....

I did this a while ago to create an infinite music machine. The chains are just based off of one particular song (Bicycle built for two, which also happens to be the song the IBM 704 sang back in the day) but could be made to work with these chords (The site appears down, so I can't access the content).

You can find the source code here : https://github.com/Feni/Infinite-Music-Machine

Well it isn't hard to figure out chord progressions, modes and key of any song. If you wish to serve 90% of the crowd, who listen to pop music, simply "catch" C Am F G type of chord progressions. For balance, you can expose and iterate with more patterns and lead yourself up to Joe Satriani/Steve Vai's of the world.

Very interesting! Although, for most common chords chart, I think that instead of simply counting the number of times a chord appears, you should have also considered the duration of that chord in the song. Didn't Pandora radio did the same analysis for its recommendation engine?

Yeah, I play guitar as just a personal hobby, and there are a lot of times when I'll play an "in between" chord on my way to the next chord I would consider to be in the progression. Many times it's not a traditional "chord" you would find in this list, but just something to bridge a key change or just create a feeling of movement.

I would say that this is most often limited to music that falls outside of pop culture, though. Katy Perry doesn't need to create movement or flow because emotional expression on the backing track is not what her music is about. The Raconteurs might, though. But once you get to that point you have to make the distinction between notes and chords.

How does this compare to what Music Theory says about chords and chord progressions? Any Music Theory experts/aficionados around? I've unfortunately forgotten most of what I learned in my one class on it.

The chord stuff is all perfectly reasonable (in pop music, that is; in a classical piece in the key of C you would have an Em going to an Am way more than to F, for example, and you'd see way more D chords).

I don't buy that Eb/Cm is the third most common key in pop music, though. There's not a whole lot of pop music in minor keys, and Eb is a weird key to play guitar in.

I like this analysis:

While I do believe the popular songs follow some pattern, I think the chord progression is only a subset. Someone should look into why Call me Maybe is so catchy. Seriously though

I would make the argument that there is little in the way of pop music that strays from traditionally accepted chord progressions. Dissonance isn't something that appeals to a broad audience, and you'll be hard pressed to find someone who can point out an interesting choice in progression for a song on the radio.

I do hear piano in Eb occasionally, but in my years of playing guitar I can't say I've ever come across it in any song I've played.
