Therefore playing tape's OK? In a way (2,2,5)
I believe the answer is:
so to speak
'in a way' is the definition.
(thesaurus)
'therefore playing tape's ok?' is the wordplay.
'therefore' becomes 'so'.
'playing' indicates an anagram.
'tapes'+'ok'='tapesok'
'tapesok' anagrammed gives 'tospeak'.
'so'+'tospeak'='SO TO SPEAK'
(Other definitions for so to speak that I've seen before include "In a way" , "as one might say" , "If one may use that expression" .)
