I believe the answer is:

sowing

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

'broadcasting' is the definition.
(broadcast can mean to sow seeds)

'music out of love?' is the wordplay.
'music' becomes 'so' (as in do re mi fa so la ti).
'out of love?' becomes 'wing' (I can't explain this - if you can you should give a lot more credence to this answer).
'so'+'wing'='SOWING'

Can you help me to learn more?

(Other definitions for sowing that I've seen before include "Broadcasting" , "Planting (seeds)" , "task in garden" , "Placing seeds in the ground" .)

I've seen this clue in the Evening Standard.
