Some reversal sadly for Latin American dance music (5)
I believe the answer is:
salsa
'latin american dance music' is the definition.
(I've seen this in another clue)
'some reversal sadly for' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'SALSA' can be found hidden inside 'reversal sadly for'.
(Other definitions for salsa that I've seen before include "dancing?" , "that's hot and saucy?" , "that's rather spicy!" , "Latin American dance - spicy Mexican sauce" , "Spicy tomato sauce" .)
