Song release on return gets slot on radio (7)

I believe the answer is:

airtime

I'm a little stuck... Click here to teach me more about this clue!

'slot on radio' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'song release on return' is the wordplay.
'song' becomes 'air' (air can mean a piece of music).
'release' becomes 'emit' (to emit is to release or let out).
'on return' shows that the letters should be reversed in order.
'emit' back-to-front is 'time'.
'air'+'time'='AIRTIME'

'gets' acts as a link.

Can you help me to learn more?

(Other definitions for airtime that I've seen before include "spell on the waves?" , "Length of a particular broadcast" , "Period of broadcast transmission" , "exposure on waves?" , "Minutes allocated to a broadcaster" .)
