All year long I went back and forth whether or not to allow this in my countdown. It had a music video released this year but the song itself was released in January of 2015. In the end I decided I wouldn't put it in the countdown, but it would have been #1 if I had so here it is.
H.M. #1 - MIIA - Dynasty
This is MIIA's first "entry" to my countdown series!
