Clue: Better music arrangement without piquancy from Red Hot Chili Peppers? (8)
Answer: CAPSICUM
Explanation: Definition: Peppers

**CAP** ("better") +***(music)** [anag:arrangement]
 
*I don't see the need for "without piquancy from" and "peppers" is plural and "capicum" is singular, so I may need some help understanding how this clue works.
