The Walking Dead Season 2 ep 5 came out
I

Indeed. I was thinking that maybe someone would have brought up an article about it or something, but yeah, this is a good part of it.

Cheers!

ive got a little grip tool i can use to strengthen my fingers until theyre calloused, it works just as good as pressing on the guitar and doesnt hurt quite as much

Don't hurt yourself.

i know

I recently picked the guitar back up. I really suck at quickly switching frets

I'm assuming you mean I-IV-V and II-V-I cadences occur in the progression rather than that being the entire progression, which if so makes you pretty well correct. II-V-I is the single most perfect cadence in all of existence, and descends from all manner of classical pieces right back to plainchant. 3 chord songs, however, are not the norm in modern culture, as you cited from the axis of awesome's four chord bonanza.
There is a marked difference between the ionian and aeolian modes, and it brings a whole different sound to go from a I-V-VI-IV four chord song to a VI-IV-I-V chord sequence instead. The sheer quantity of "sad" four chord songs and "happy" four chord songs should make it pretty clear that changing the scale and the mode definitely brings an alternative motive to a piece. Don't forget, however, that when talking about the scale of any minor, there is often a raised seventh in the melody (in A minor's case this is a G#), to reaffirm to the ear that the root of the scale is there. It is absent from a lot of contemporary music, however, since songwriters prefer to have the major/minor ambiguity to leave them more room for chords.

not as nice as being a hairy werewolf, bite me.

Go on.

a hairy werewolf biting you is not something you would enjoy

Some people would enjoy it.
