Type of music depression (5)
I believe the answer is:
blues
This clue is a double definition.
'type of music' is the first definition.
(I've seen this in another clue)
'depression' is the second definition.
(I know that blues is a type of depression)
(Other definitions for blues that I've seen before include "Depression - music" , "Lady Sings the - - (film)" , "Jazz classic (2,5,5) - See 9" , "Oxbridge athletes" , "Feeling of sadness or depression" .)
