Rooms for artists at radio station? (7)
I believe the answer is:
studios
I believe this clue is a double definition.
'rooms for artists' is the first definition.
'radio station?' is the second definition.
(as in radio studios)
'at' is the link.
(Other definitions for studios that I've seen before include "Artists' workrooms" , "Places where artists or TV performers work" , "Ateliers" , "makers of movies" .)
