Source of music in Antipodes (4)
I believe the answer is:
ipod
'source of music' is the definition.
'in antipodes' is the wordplay.
'in' says the answer is hidden in the clue.
'IPOD' is hidden within 'antipodes'.
(Other definitions for ipod that I've seen before include "Music player" , "Brand of portable digital media player" , "listening device" , "Familiar gadget" , "Pocket-sized device for playing music" .)
