Show jazz inspired by heavy metal – it’s what good consumers prefer (4,5)
I believe the answer is:
fair trade
'what good consumers prefer' is the definition.
I can't tell whether this definition defines the answer.
'show jazz inspired by heavy metal' is the wordplay.
'show' becomes 'air' (both can mean broadcast).
'jazz' becomes 'trad' (trad jazz is a type of jazz).
'inspired by' means one lot of letters goes inside another (some letters breathed in or 'inspired' by others).
'heavy metal' becomes 'Fe' (chemical symbol for iron).
'air'+'trad'='airtrad'
'airtrad' going inside 'fe' is 'FAIR-TRADE'.
'it's' is the link.
Can you help me to learn more?
(Other definitions for fair trade that I've seen before include "Ethical form of commerce" , "A dirt fear (anag.)" , "Ethically sourced" , "Honest dealing" , "principle of decent business deals" .)
