Songs openly blasting on every one of the commercials (7)
I believe the answer is:
ballads
'songs' is the definition.
(ballad is a kind of song)
'openly blasting on every one of the commercials' is the wordplay.
'openly blasting on every one of' becomes 'ball' (I can't explain this - if you can you should believe this answer much more).
'the commercials' becomes 'ads' (I've seen this before).
'ball'+'ads'='BALLADS'
Can you help me to learn more?
(Other definitions for ballads that I've seen before include "Soppy songs!" , "Popular songs" .)
