"Don't Know Why" by Jesse Harris performed by Norah Jones has chord strength.

Written by Jesse Harris (both words and music!) and performed by Norah Jones in 2002-- 12 years ago now!?-- this song has some substance. I could tell when I first heard it. The reason is that the chord progression is literate and makes sense-- yet is original. Here it is...

IM7 - I7 - IVM7  - III7 - vi7 - II7 - V7sus - V11

I'll throw more samples onto a play list with that above video kicking it off in coming days.
