Walking, coughing in the streets.
If Mario Wienerroither walked into a TV producer's office in Hollywood and said, "I'd like to remove the music from classic music videos and replace it with completely ordinary sound effects," the producer would most likely nod his head politely and say "Uh huh, sure... I'm listening," while texting an assistant instructions to interrupt the meeting and never again take Mario's calls.
Which is why the single greatest thing about the internet is that not one idea, no matter how ridiculous it sounds, can be rejected. Allowing for visionaries like Mario to pursue their absurdly brilliant ideas and produce video shorts like "Dancing in the Street" without music. Enjoy.
