Why does all new pop music sound the same?


Basically because it IS the same - I think anyone with ears already knows that, but there is more to it.

@boxer12 , it's what you said. This CAN go both ways but I think it's important to take as much as we want to give. You are showing an interest in what your kids are listening to and what's important to them musically and in turn they are doing the same. There are correlations between the bands you've listed and many deviations which could occupy a lifetime of exploration.

A great way to introduce older bands is through covers... Phish does this well...sneakin' sally through the alley, VU- loaded, TH- remain in light, boogie on reggae women, etc. Jim James and Mark Lanegan have both released cover albums. Many of the current indie bands released the massive GD tribute produced by by The National.

Hearing Phish play Sneaking Sally, I dug further and found Robert Palmer (the Robert Palmer I grew up with was addicted to love and letting the world know that some like it hot, not the 70's sneakin' sally and Pressure Drop Palmer I came to love.) I then dug further and found Allen Toussaint, who wrote the song. He exposed me to the NOLA sound and I became a fan of Professor Longhair, the Meters, Dr. John, Lee Dorsey, etc...

Well , I believe that the standards are set by the likes of  "The Idols" reality TV programs all over the world and everybody think that is the "sound" that will make it onto becoming world famous or at least famous in their own countries. If you have noticed, there are very little distinction between the winners year after year. 
It's crap.....    My kids are 19 and 22.   Their choice in music is pretty bad.   Although my daughter likes some classic rock ...Fleetwood Mac, Tom Petty,  so that's a good sign.... 

My son is into rap,  hip hop.....  I'm no prude , believe me but I blush at some of those lyrics....   

Everything is mixed to sound best on lesser systems in my opinion.
Jkotze.... you are right on the money...it's like a template or formula.   It's not great songwriting
