Show's intro gets me mostly hot ‘n' bothered (5,4)
I believe the answer is:
theme song
'show's intro' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'gets me mostly hot n bothered' is the wordplay.
'mostly' means to remove the last letter.
'bothered' indicates an anagram.
'hot' with its last letter taken away is 'ho'.
'gets'+'me'+'ho'+'n'='getsmehon'
'getsmehon' is an anagram of 'THEME SONG'.
Can you help me to learn more?
(Other definitions for theme song that I've seen before include "Signature tune" , "Give me Sunshine" , "Characteristic melody often repeated in musical" .)
