Dance record leading to love (5)
I believe the answer is:
disco
'dance' is the definition.
(disco can mean a dance event)
'record leading to love' is the wordplay.
'record' becomes 'disc' (synonyms).
'leading to' is a charade indicator (letters next to each other) (some letters go before or lead others).
'love' becomes 'o' (love means zero in tennis).
'disc'+'o'='DISCO'
(Other definitions for disco that I've seen before include "Demonic spirit" , "Nightclub with dancing to recorded music" , "Place to dance to recorded music, in short" , "Style of music/dancing" , "lively entertainment, for some?" .)
