Floor singers who plead for "just two very short songs" - they never are.
Floor singers who roll two songs together into one - this is taking the piss, in my view.
Floor singers who, knowing that time is short, sing an interminable song well beyond the allotted time.
Singer/songwriters whose songs are filled with the same choruses repeated over and over again, interspersed with noodling, uninteresting guitar work, and which drone on for ever.">

Spot on, Will, especially the first one.
