Online rap played without equal (9)
I believe the answer is:
nonpareil
'without equal' is the definition.
(I've seen this before)
'online rap played' is the wordplay.
'played' is an anagram indicator.
'online'+'rap'='onlinerap'
'onlinerap' anagrammed gives 'NONPAREIL'.
(Other definitions for nonpareil that I've seen before include "ideal" , "beyond compare" , "Unrivalled; old type size" , "Unequalled" , "Peerless" .)
