Regular new age music (6)
I believe the answer is:
reggae
'music' is the definition.
(reggae is a kind of music)
'regular new age' is the wordplay.
'regular' becomes 'reg' (I can't justify this - if you can you should believe this answer much more).
'new' is an anagram indicator.
'age' with letters rearranged gives 'gae'.
'reg'+'gae'='REGGAE'
Can you help me to learn more?
(Other definitions for reggae that I've seen before include "W.I. music" , "A Caribbean music style" , "Popular music of the West Indies" , "Bob Marley's music" , "Music style from Jamaica" .)
