“One chord is fine. Two chords are pushing it. Three chords and you're into jazz.” -Lou Reed
See, I have a hard time with your first paragraph. The premise seems to be simple = bad & complex = good, or at least complex can't = bad because it's complex, or should be spared from criticism because it's complex. I disagree. A simple 3 chord pop song can hit emotionally the same way a simply but beautifully prepared plate of pasta with 3 or 4 ingredients can hit your palate: pure pleasure; whereas a complex song can fall completely flat, be forgettable or even outright unpleasant, the same way an over-complicated fusion dish trying to do too much can miss out on why people eat food in the first place - because it tastes good. While this is only my opinion, being a wildly talented musician does not at all save you from making bad music.
You're saying the exact same thing. He just said it semi-sarcastically. I will say, independent of taste, the
musicians in RHCP are masters of economy/groove while being wildly talented, not that I'd point to that song. I think DP's point was wildly talented musicians still often trade in similar simple progressions. You could do a 40 minute video ripping "Smells Like Teen Spirit," if this is the extent of the argument. Cobain was a master at using the architecture of pop songs. It's why criticizing that is missing the entire point (a point that applies to movies, etc.). Usually what it boils down to is this: a song is popular, trading on things that make music popular, ipso facto it sucks. Sometimes they do, sometimes they don't, factor in taste, but that's
never the reason.
The "ripping" argument is one I particularly enjoy, but we don't need to get into that
"I wrote a song with this progression in high school" or saying "this is how they should have done the bass" are just wooooooosh statements to me, said partially for effect or not. And if you're going to use those arguments, there's better choices than some of the most talented musicians on their instruments to ever do it.
