Why does most new music suck?

What really sucks is the pandering, witless, sfb, utterly mercenary "classic rock" radio stations that are nothing better than 60's am radio with marginally better sound. 
I don't like rap but it deserves its place in the pantheon simply because it's still here - and amazingly popular - current popular r&b is...popular. I may not get it, or appreciate it for that matter,  but the guard has changed and I missed it. I don't miss missing it, either.  
My parents thought "my" music sucked - that's the way it should be!

I find very little rap or hip-hop that doesn't annoy or offend me.  I don't think of it as music at all--it's rope-jumping rhymes with loud percussion accompaniment.  I do like some recently-produced music, usually some sort of alt. rock or pop.  Anyway, I listen more to classical than popular music these days. 

I find some truth in this oversimplification:
Rap--people talking when they should be singing
Opera--people singing when they should be talking

I don't know much about anything but Classical but I do know I would much rather listen to the best of rap than the best of rock.

Far more intelligent, relevant and creative IMO .

Interesting observation by Schubert.  Rap/hip hop strikes me as much closer in spirit to 1950s Rock n Roll than most other contemporary music.  On the whole, it's been significantly more counter-culture than most other pop music forms that have come and gone since then.   Like the message or not, at least it has something to say.  Rock music has produced a fair number of virtuoso players over the decades, but you can argue that that sort of misses the point.  None of this music need necessarily be about technical competence.

However, little hip hop resonates with me.  While that doubtless says more about me as a listener than it does about the music, it also speaks to an earlier argument made in this thread:. As we get older, we listen differently.  Some have suggested that we listen with a more discerning ear, but it's also likely that we listen with a less open mind - and I plead guilty to that, as well.

Rap is more expressive story telling accompanied by music.  Some similarity to the blues there.

Rock is more about an expressive musical style accompanied by lyrics.   

They all have lyrics and convey messages but the messages differ in terms of the culture influencing them and that of the target audience.

Like reading a book, listening to music is a way of hearing about the experiences of others and relating to those perhaps in some way.  Rap is well designed for this it seems to me.  The music serves more as an accompaniment than it is the feature.  Kind of like a more rhythmic form of ballad.
