Record sounds grubby (5)
I believe the answer is:
seedy
'grubby' is the definition.
(thesaurus)
'record sounds' is the wordplay.
'record' becomes 'cd' (compact disc).
'sounds' shows a homophone (sound like).
'cd' is a homophone of 'SEEDY'.
(Other definitions for seedy that I've seen before include "run down" , "Out of sorts" , "Not well turned out" , "Sordid, squalid" , "Dilapidated" .)
