These are loose terms admittedly and it is debatable whether Indie is actually a genre or not. Having said that, most people use Indie as an umbrella term for a genre anyway so that is why it was included. And please, don't give me anymore lectures about how it shouldn't be included because it is not genre because you've made your point already.
I'm not here to argue about genres but everything from Decemberists to Cafe Tacuba is considered "indie". Knowing this, it's hard to vote..
I could go on all day. Folk is without a shadow of a doubt my favorite musical genre of all time. I am of the belief that music should be something that tells a story, something that gets you emotionally invested as opposed to over-produced autotuned hit-of-the-week music that is just produced to sound good. I'll take a bootlegged Jackson Browne concert recorded with a potato over most stuff that is produced these days.
