Runs into no popular music? Things are flat around here (7)
I believe the answer is:
norfolk
'are flat around here' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'runs into no popular music?' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'into' is an insertion indicator.
'popular music?' becomes 'folk' (folk is a kind of music. I am not sure about the 'popular' bit.).
'no'+'folk'='nofolk'
'r' inserted into 'nofolk' is 'NORFOLK'.
'things' acts as a link.
Can you help me to learn more?
(Other definitions for norfolk that I've seen before include "It has much farmland" , "English county containing the Broads" , "Very flat county" , "Broad area" , "Agricultural county; type of jacket" .)
