You've got me thinking bout minor keys. Sure, there's some popular tunes in  minor, but if you listen to the radio, you're not gonna hear a 50/50 balance between major and minor keys. It'll probably be more like 90(maj)/10 (min)? Like I was paying attention on my car ride to work this morning and I didn't hear 1 song in a minor key. I also think that a lot of the songs that are in minor have a strong pull towards the major chords in the key (like songs in Amin really wanna hang on that Cmaj at some point), and a lot of songs that could be minor have more of a minor pentatonic/blues scale feel than straight up minor.
i agree completely with all of that
