Why does all new pop music sound the same?

Current American top 5 pop songs, week of 30Dec17:

1. Ed Sheeran -- Shape of you
2. Bruno Mars -- That's What I Like
3. Zedd and Aleissa Cara -- Stay
4. Kygo and Selena Gomez -- It Ain't Me
5. Aleissa Cara -- Scars to your Beautiful

Full disclosure, I really do not care for this type of music.  Also, I know the above is a snapshot and not representative of "All modern pop", but this somewhat validates the argument.  All "clubish" type compositions. I do not think they all "sound the same" though, but certainly this is the genre that is currently popular, so the songs will be similar.

Interestingly, NOT all written by the same two guys though.

Also, remember Post grunge? Hair metal? Disco? Bubblegum? Modern country? Boy Bands? Swing? Once these styles became popular and over saturated, I would argue the discussion was exactly the same. 

My point is, it really doesn't matter how many people write the songs, once it becomes "popular", and all the trappings that the label implies, it becomes restricted in content and formulaic. It's the American way. This isn't a new situation. Pop music has sucked forever. 

I look back fondly on the early '90s, as a time when there was an explosion in music variety.  Nirvana, Smashing Pumpkins, Green Day, etc. Rock had a revolution!!!...

...and then I look back on the charts.  Oh nuts. It was filled with Boyz II Men, All 4 One, Brandy, Aaliyah, Monica, En Vogue, TLC...

This too shall pass, but the complaining won't.  

So I guess we should all move to Finland? 

Agree for sure. Just spent about 40 minutes with Ed Sheeran during lunch on the Bluetooth set up. Not my favorite by a long shot. Family likes him though, so it's fine. At least we are listening to music, right?

Face it, this music isn't made for us. It's ok to be a snob.
