I just can't get into guitarists like Steve Vai, Yngwie Malmsteen, Stevie Ray Vaughan, etc. I can't even get into John Mayer (though he can be more tasteful with his improv). It's all just a big dick-measuring contest. Believe it or not, this is not meant to be ironic: https://www.youtube.com/watch?v=46qjDJ0lLdE
Give me Townes Van Zandt, Leonard Cohen, Neil Young, Joni Mitchell - all fantastic *songwriters*. The Beatles have so many simple songs - eg Blackbird (simple two note chords), Twist & Shout (three chords), etc, but they're all beautiful and will live on forever. I cannot imagine people listening to Steve Vai in 50 years, because I can't imagine why people listen today.
