Americans enjoy this wretched dance (8)
I believe the answer is:
baseball
'americans enjoy this' is the definition.
(sport popular in the USA)
'wretched dance' is the wordplay.
'wretched' becomes 'base' (both can mean horrible or immoral).
'dance' becomes 'ball' (ball is a kind of dance).
'base'+'ball'='BASEBALL'
(Other definitions for baseball that I've seen before include "Lea blabs about the sport" , "American game like rounders" , "Nine-a-side game" , "Sport played with a bat" , "SPORT/GAME" .)
