Why does all new pop music sound the same?

Getting back to the original question...  "Why does all new pop music sound the same?"
ANS:  If you restrict your effort to discover new music to boring pop-schlock on playlist radio and the muzak at K-Mart, it does mostly sound alike.  Worse, the bean-counters at the big music publishers and distributors have gotten it all down to a dystopian econometric algorithm of hooks and catch phrases.  If you listen a bit to promoted hits, most of them lack an actual discernible melody.  All they are is a string of hooks and psychometrically-validated snippets strung together to create the illusion of music.  Most devolve down to a sing-song cadence not far dissimilar to what 5 year-olds drone on the play-yard.  The more mainstream "popular" an artist is, the more and more indistinguishable is each successive "hit" promoted to mass sound (as distinct from music) outlets.  It is no longer "music" per se but "product", much the same that the corporate over-class foists upon the consuming public (visions of sheeple grazing at McDarnold's intrude at this point).  At another extreme of clone-ish music is most of what is electronically mass-produced for the dance club and rave scene, so dominated by what sounds like a single universal drum machine track.  But even here, there are pearls to be discovered.

Fortunately, there is still a surprisingly vast world of new music these past couple decades that has given birth to dozens of new concepts and genres.  "Pop" does not even begin to encompass the amazing range and variety of music available to the audiophile of today.  I offer the following as a tiny hit of "pop" tunes (broadly speaking) as pudding proof.  All are easily find-able on the Net...   in no order of preference ...

• Schnitz!   by  Dorfmeister vs. Madrid De Los Austrias (LoungeMasters Music Video)
• Arabian   by  gusgus (KEXP Lively Session)
• John Lee Huber (Radio Edit)    by TOSCA
• Beautiful Things (DJ Tiesto Mix)    by Andain feat. DJ Tiesto
• Hey Now    by London Grammar (album vers. & KEXP live session on YouTube)
• Tricky Tricky (Salem's remix)    by  Röyksopp

• Stof    by Eefje de Visser (MV on YouTube)
• Crystalfilm (EP version)   by Little Dragon

Pop music sounds alike???  Surely this was a rhetorical question. 

'Nuff said.

@inna  yours is a Beautiful illustration of the @chayro point made a day-two ago that you cannot say ANYTHING without being ridiculed!

I will bite... for one, Finnish language is the only language Not having any roots in any other Human languages, no explanation to this glitch found so far. Except that maybe somehow the folks there survived the latest Ice Age 12-13 thou years ago and kept talking...

Second, (and not that I care): I had a misfortune of traveling all over the globe and somehow I still fondly remember me visiting Karelia (piece of Finland grabbed by Russians), so the snippet about Finland being whatnot or whatthat feels a bit, how to put this, f#$%^-&*... But I have no doubts that all Finns are dreaming about visiting 5th Ave or Beverly Hills or experiencing the world-famous Hwy 405 traffic here... ;-)

Finnish language belongs to Uralic language group, along with Hungarian and Estonian.
The oldest spoken European language isolate is Euskara, Basque language.
First learn things then speak.

I like the sound of my story better, so I will stick with it, not with Google. And before you ask, yes the Earth is flat! I am one of those...
Glad that my bad and your generous wisdom illustrated my original point, once again.

Schubert,

Hei terve! (Hello!) Thank you for your kind response to my recent post. I've heard very similar responses from everyone I've spoken to who has visited Finland. Interestingly, Finland is a lot like my home state of Maine, with most visitors stating, "If only they could live in Maine". I've visited Finland three times and am always planning my next visit.  Each time we've always included a week in a second Nordic country, Denmark, Sweden, Norway and day trips from Helsinki to Tallinn, Estonia by high speed ferry.  A lot can be experienced in a day with 20 hours plus of Summer sun!  Extended stays in Finland have included Helsinki, Joensuu, Kuopio, Savonlinna and Kerimäki.  In full disclosure, my planning centers around the live concert schedules of my favorite recording artists. No matter the location of the live performance, there are always uncrowded historical sites, museums and restaurants nearby.

Nearly as entertaining as the live music, sitting in public spaces or cafes listening to the local women and girls engage in conversation. The spoken Finnish language, combined with the pitch and cadence of the female voice is very musical and pleasing to listen to. That observance, combined with the desire to understand song lyrics and engage in meaningful conversation has led me to enroll in formal Finnish language classes and attend an upcoming 40 hour language "boot camp" in June 2018.

If you would be so kind, would you forward to me the names of the Finnish tango artists you spoke of in your reply?

If you are interested, I purchase newly released Finnish recordings from, yes, a real brick and mortar music chain in Finland called Record Shop X. I've visited the stores in Helsinki and Kuopio and have engaged in enjoyable and wide ranging conversations with the employees in both. Purchases typically arrive in seven days and I've never had an issue with a transaction, the business accepts PayPal. https://www.recordshopx.com

Hyvää illanjatkoa! (Have a nice evening!)  Or, depending on your time zone.  Hyvää yötä! (Good night!)
