Happy and relaxed after a record return (7)
I believe the answer is:
pleased
'happy' is the definition.
(similar in meaning)
'relaxed after a record return' is the wordplay.
'relaxed' becomes 'eased' (I've seen this before).
'after' says to put letters next to each other.
'a record' becomes 'L-P' (abbreviation for long play record).
'return' is a reversal indicator.
'lp' backwards is 'pl'.
'eased' after 'pl' is 'PLEASED'.
'and' is the link.
(Other definitions for pleased that I've seen before include "Euphoric" , "like Punch?" , "Feeling satisfaction" , "Content" , "Glad" .)
