You don't have to pay to mute them. Just go into System Configuration - Sound - and mute Performance.
As for paying you because you don't like them, that's never going to happen. Players abuse those sorts of systems. One of the indie developers that makes some of the most positively reviewed games on Steam just recently stopped making more games. Why? Because his games were very short when it comes to time played and players were abusing Steam's refund policy once they finished playing to get the refund even though they enjoyed the game.
Likewise, we would see players who liked a Bard's performance say it sucked just get whatever gil the game would give them for saying it sucked.
