So I just started studying music theory, so for fun I thought I would practice by analyzing a song I remember enjoying. Marianas Trench's satirical song "Pop 101":
The song suggests using the chord progression I - IV - vi - IV. Because the song is a satire, I assumed this meant they think the chord progression was overly used in pop. However, I'm struggling to find any examples of songs using it. The progression I - V - vi - IV seems much more common, and I know how to square this with "common practice". I don't know how to make sense of "IV - vi" step with my beginner text.
Is it possible they made a mistake and ran with it? Or are there a ton of songs in I - IV - vi - IV that I'm just failing to find?
