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
