It isn't at all a shot toward the limitations of the music â€“ but in terms of lyricism, rock and roll songs tell stories that live on forever, hence the extreme lasting value of musicians like The Beatles or Bruce Springsteen or even the countless artists that influenced them. This happens in blues, soul, etc., too. Dance music, electronic music and to a lesser extent, radio pop, are much more likely to have lyricism that throws away a timelessness in exchange for a "live in the moment" type freedom. Absolutely not a bad thing â€“ obviously there is a place for that. I think it's pretty well noted that the cultures of these genres are different, and I'm not at all saying that I made some sort of big revelation there, but that's what I was going for in that closing paragraph.
That's pretty dismissive as a whole, regardless of how you intended the sentiment, and I'd rather have the lyricism of a handful of electronic artists over the trite offerings here.
