Playing the oldies I love (7)
I believe the answer is:
idolise
'love' is the definition.
('love'->'idolize' is in my internal thesaurus and 'ize'->'ise')
'playing the oldies i' is the wordplay.
'playing' is an anagram indicator.
'oldies'+'i'='oldiesi'
'oldiesi' anagrammed gives 'IDOLISE'.
(Other definitions for idolise that I've seen before include "Hero-worship, revere" , "Worship (S, not Z)" , "Revere (someone) greatly or excessively" , "Worship extravagantly" , "Pay inordinate attention to" .)
