Vulgar recording ensnaring a beautiful person (7)
I believe the answer is:
caddish
'vulgar' is the definition.
(thesaurus)
'recording ensnaring a beautiful person' is the wordplay.
'recording' becomes 'CD' (type of recording).
'ensnaring' means one lot of letters goes inside another.
'beautiful person' becomes 'dish' (dish can mean an attractive person).
'cd' going around 'a' is 'cad'.
'cad'+'dish'='CADDISH'
(Other definitions for caddish that I've seen before include "Misbehaving" , "Ungentlemanly sort of behaviour" , "Like dishonourable men" , "like Terry-Thomas?" , "pretty low" .)
