Arranged rags in one music genre, and another (9)
I believe the answer is:
bluegrass
'genre and another' is the definition.
I can't judge whether this definition defines the answer.
'arranged rags in one music' is the wordplay.
'arranged' is an anagram indicator (letters rearranged).
'in' indicates putting letters inside.
'one music' becomes 'blues' (blues is a kind of music).
'rags' anagrammed gives 'gras'.
'gras' inserted within 'blues' is 'BLUEGRASS'.
Can you help me to learn more?
(Other definitions for bluegrass that I've seen before include "Style of country music from Kentucky" , "Style of US country music" , "nickname of US State" , "A type of country music" , "Kind of country music" .)
