Right in the feels. BoySetsFire and Snapcase were both fucking awesome. Poison the Well was also awesome. That whole period of my life, going to shows like that, was probably the only time in my life I ever actually had fun.
Anyway,
That said, best songs ever is so hard because every era of music is so different and it's so difficult to compare across generations.
1960s:
Jefferson Airplane - White Rabbit
1970s:
The Who - Love, Reign O’er Me, but whomever said Kashmir that could also be it.
1980s: Very difficult to pick one. When I think 1980s I immediately think of
GnR - Paradise City or Bon Jovi - Livin' on a Prayer so either would work. Honorable Mention: Fight the Power.
1990s:
Foo Fighters - Everlong and it's not that close. jk, it's kinda close. Otherside, Enter Sandman, quite a few good runners up.
2000s:
MGMT - Electric Feel or something from Gorillaz. 2000s is a tough decade, needs to stew for a while.
2010s: Taylor Swift - Style
jk it's Paramore - Ain't It Fun.
2020s: Sucks total ass so far.
