TOP TIER
Would listen to sober
FINE TIER
Would watch at a festival while moderately drunk and would know the words to at least 2 of their songs enough to kind of sing along
FUNNY TIER
Would pull up as an example of how stupid it was to be a teenager in the late 90s / early 2000s.
BAD TIER
Would probably chuckle if they came on in a bad rock club.
ERASE TIER
I mean…sometimes bad is just bad isn’t it.
Behold the application of science.
