Shake – music genre (4)
I believe the answer is:
rock
I believe this is a double definition.
'shake' is the first definition.
(I know that shake can be written as rock)
'music genre' is the second definition.
(I know that rock is a type of popular music)
(Other definitions for rock that I've seen before include "Shake; boulder" , "Brighton sweet?" , "startle" , "Seaside confectionery" , "Pop; precious stone" .)
