Yes, technically the #1 chord progression in pop music but there's more to it than that. You get 22 chord structures with midi as well as a corresponding audio file. The midi is more valuable than audio in this case IMO. Most of the audio is simplistic, piano chords, pad and a synth. Some of the loops are more intricate and have variation in the sounds. There are major an minor variations to give you versatility. For those who want quick inspiration or don't have much musical knowledge, this is a nice tool to have in your arsenal.
