Popular country singer makes list (7)
I believe the answer is:
incline
'list' is the definition.
(list can mean to lean or roll)
'popular country singer' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'country singer' becomes 'cline' (Patsy Cline, 1932-1963).
'in'+'cline'='INCLINE'
'makes' acts as a link.
(Other definitions for incline that I've seen before include "Tend; lean" , "Bend forwards" , "Have a tendency to do or be something" , "Have tendency or slope" , "tip" .)
