Why is modern pop music today so terrible?

Surprisingly, I always liked Bach. Puts me to sleep easily, though. There were others in his time, however, don't remember the names. I heard their music too, Bach was better, to my mind.

Sir Sly - Don't You Worry, Honey
I think that's a great modern indie-pop LP.
If you haven't listened to it already, give it a whirl; might give you some hope for modern pop and the direction it's heading.
Also: Paramore - After Laughter
That's a little pop as well, but not an awful lot, it's pretty quirky :)

I'll go with one explanation that hasn't been proffered yet - changing taste in recreational drugs.

Back in the day, downers and hallucinogens sparked a more pensive or spacey (respectively) artistic impulse.  Today's turbo charged uppers produce 200 bpm EDM.  It's especially tough on us old guys who can't listen that fast.

I thought we're talking about popular music. 
Popular music has it's own agenda to be popular and targeted to uninformed crowd at all times. Any idea why Leonard Bernstein was NOT part of Boston Pops? I guess because music isn't really part of radio pop and it's definitely a separate meaning.
Tchaikovsky back in his days published piano pieces 12 Months in 12 journals so that casual and barely trained person could entertain oneself with relatively easy sheet music.
Today there's no need to know sheet music, because it could be heard on radio and radio is guilty of all charges to deliver popular music. I had music basics as a school curriculum to know basics of SolFegio, therefore I guess I value complexity and effort to play certain piece or perform. 
Did anyone enjoys David Rose or Ray Conif? That stuff will trigger my "wtf am I listening to..." phrase. It's pop.
