I don't think it's that much of a crime to call a piano song "a piece"  
	I do bealive it is the most beautiful piece ever written, so I don't feel regrets calling it that 
	but even if I didn't it's youtube, people sometimes use catchy titles, no need to go insane about it 
	I undrastand that you're trying to help, but that's not how I'd define support.  
	same with reason three, yes, I make jokes, yes, I don't explain every little thing like a harvard composition teacher, again  
	it's a youtube video
