A lot of the stuff in the top 20 I remember playing on college radio in the late 90s. My view of emo at the time was mostly midwestern 20 somethings playing somewhat angular indie rock that girls liked. They were influenced by Sunny Day Real Estate and Minor Threat, sometimes they sang, and sometimes there was a screamy guy. Sometimes it was pop punk with some math rock cords and timing for variation. I liked Braid alright, they seemed really influenced by Jawbox. I never considered Drive like Jehu to be emo, or Dismemberment Plan, who toured with some emo bands. Most of the ones on that list, I never listen to now.
I never understood the whole goth = emo thing in the 2000s. To me goth is Bauhaus or Dead Can Dance or some Siouxie Sioux, nothing I would remotely equate to emo.
