To put it differently, one is not hot on Queen lyrics (2,5,5)
I believe the answer is:
in other words
'to put it differently one' is the definition.
I can't judge whether this defines the answer.
'not hot on queen lyrics' is the wordplay.
'not' becomes 'oth' (I can't explain this - if you can you should believe this answer much more).
'hot' becomes 'in' (both can mean fashionable).
'on' says to put letters next to each other.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'lyrics' becomes 'words' (I've seen this before).
'oth' after 'in' is 'inoth'.
'inoth'+'er'+'words'='IN OTHER WORDS'
'is' is the link.
Can you help me to learn more?
(Other definitions for in other words that I've seen before include "Put differently" , "Expressed alternatively" , "Expressed differently" , "Viz" , "Putting it differently" .)
