i really appreciate this it sounds awesome. I'm still a beginner so if anyone else wants to try E7 instead its easier:
A - 2
E - 0
C - 2
G - 1

I like this way better than the other chord set that I find all over the internet - I think it sounds better and works better for sining, at least for me. Great job!

i think the other one sounds good and is less complicated.

If you were wondering i play Aadd9 like this :)
A - 2
E - 0
C - 1
G - 2
