Teen songs with incoherent, lovey-dovey words (5,8)
I believe the answer is:
sweet nothings
'lovey-dovey words' is the definition.
'sweet nothings' can be an answer for 'words' (I have seen 'Words of affection ' mean 'sweet nothings' so perhaps 'words' could also mean 'sweet nothings'). I'm not certain of the 'lovey-dovey' bit.
'teen songs with incoherent' is the wordplay.
'incoherent' indicates an anagram.
'teen'+'songs'+'with'='teensongswith'
'teensongswith' is an anagram of 'SWEET NOTHINGS'.
Can you help me to learn more?
(Other definitions for sweet nothings that I've seen before include "Lovers' words?" , "Loving words" , "Amorous burble" , "whispered words of affection" , "romantic words" .)
