Unsingable

What can make a song unsingable? What can make a song feel lost? What can make it inconceivable? To play for any cost? And what's enough? And what's "a lot?" What is going too far and what is not? What's dignified? What's just a pose? Anybody knows What can make a song unbearable? What has nothing more to say? What can make a song unshareable? What's too far away? And what's enough? And what's a show? Where's that lying tongue I used to know? Here, tie this rope around it Don't be slow Let it rip Let it flow Like a coin-toss pool mosaic A bit profound, a bit prosaic Count to four I'll prove to you: How a song becomes untrue
