Sort of rock song collection put together for radio (7,3)
I believe the answer is:
crystal set
'radio' is the definition.
(I've seen this before)
'sort of rock song collection put together' is the wordplay.
I cannot really see how this works, but
'rock' could be 'crystal' (crystal is a kind of rock) and 'crystal' is located in the answer.
'collection' could be 'set' (set is a kind of collection) and 'set' is located in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for crystal set that I've seen before include "matching items of glassware?" , "Receiver" , "Radio" , "Matching glasses" , "used to receive long ago" .)
