Fated to perform, engaging individual that's musically challenged? (4-4)
I believe the answer is:
tone-deaf
'musically challenged?' is the definition.
(I've seen this before)
'fated to perform engaging individual' is the wordplay.
'to perform' indicates an anagram (I've seen 'performing' mean this).
'engaging' indicates putting letters inside.
'individual' becomes 'one' (an individual is one person).
'fated' is an anagram of 'tdeaf'.
'tdeaf' enclosing 'one' is 'TONE-DEAF'.
'that's' acts as a link.
(Other definitions for tone-deaf that I've seen before include "can't discern pitch" , "Not able to distinguish pitches" , "Unable to appreciate music" , "Unable to perceive musical pitch accurately" , "Without musical appreciation" .)
