Beats arrangement from Wet Wet Wet we always dismissed? (6,4)
I believe the answer is:
triple time
'beats arrangement' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for triple time that I've seen before include "What waltzers keep" , "a very high rate of pay in unsocial hours?" .)
