hey, this is just Fan-Based.
1. it's just majority who will win
2. Did I say JUST ?

Therefore, Majority based voting means who you like and not generally the best.
Although Taylor has many fans, and can write amazingly, but the fact is, she can't sing! (duh!) NO OFFENSE. But compared to Carrie, hey, Carrie can write too. How many Carrie singles (written) topped the chart, all, 100%. Unlike OTHERS! (~,~)

It's just a fact, never believe in most (not all, like american idol, ACM--it's very prestigious) fan-based award-giviing bodies*, they're just minor sucking awards show...
Believe in the Award-giving bodies that really study artists and songs that should really be credited like Grammy, ACM, CMA, etc.

*for ACM since the Entertainer of the Year and New Artist are being fan-voted, but still, nominees undergo through a needle's eye to become a nominee.
