I'm a fan (and you should be too) because...I don't know if you should be for my reason but although I've had my favorites over my life time, AK is the first artist who has created an album that I can actually relate to lyrically and she continued to do that all the way up to now. Oh my goodness definitely now. Blame it on the actual age group. My other favs were already grown when I was coming up.
Besides that the music is top fricking prime. Listen for the changes in the drum work, the strings, the brass, oh my goodness let me stop now. I could go on.
