Is popular music nowadays worse than it was before?

I believe that, although the themes of popular music have not changed in decades - sex and power being prevalent themes throughout - , the expression of these themes has changed so that modern popular music is more simple than in past years. For instance, modern musicians tend to veil their references to sex more and more thinly, leaving little to their audience's imagination or their ability to interpret: Consider the explicit, bare line "pussy put his ass to sleep, now he calling me Nyquil" from Nicki Minaj's "Anaconda" as opposed to the titular innuendo in AC/DC's "You Shook Me All Night Long," which is itself thinly-veiled compared to the line "Don't keep me waiting when I'm in the mood," from Glenn Miller and The Andrew Sisters' "In the Mood," which hides its sexual undertones with discussion of dancing. For this reason, that modern artists expect less from their audiences and thus produce a simpler product which in turn (I believe) simplifies society, I believe that popular music is worse nowadays than it was before.
