My two favs to pull out on other music fans that get them worked up:
Live Through This > Bleach, Nevermind, In Utero
or more bluntly
Hole > Nirvana
and
James Brown was much more influential and important than Beatles
That last one is just a fact. I don't hate the Beatles at all and I think the trendy hating on the Beatles train is misguided as it's pretty stupid an arrogant to deny that the Beatles had a massive global impact on pop music. The thing is, I'd argue Brown had equal the impact globally, and his innovations actually lasted longer. His emphasis on rhythm started in the late 60s continues to define popular music worldwide, while less and less people care about concept albums from white dudes in costumes.
On a point of equality, James Brown and John Lennon were both horrible people outside of their music.
