Tape playing with superb content (2,5)
I believe the answer is:
at peace
'content' is the definition.
(similar in meaning)
'tape playing with superb' is the wordplay.
'playing' indicates an anagram.
'with' says to put letters next to each other.
'superb' becomes 'ace' (ace can informally mean very good).
'tape' is an anagram of 'atpe'.
'atpe'+'ace'='AT PEACE'
(Other definitions for at peace that I've seen before include "In a state of serenity" , "Resting serenely" , "no longer with us" , "Not disputing" , "calm" .)
