Remarks directed to audience for the better songs (6)
I believe the answer is:
asides
'better songs' is the definition.
(as opposed to B-sides)
'remarks directed to audience for' is the wordplay.
'remarks directed to audience' becomes 'aside' (as in an aside in a play).
'for' becomes 's' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'aside'+'s'='ASIDES'
'the' is the link.
Can you help me to learn more?
(Other definitions for asides that I've seen before include "Words spoken from corner of mouth" , "Words spoken on stage" , "Stage whisper" , "Incidental remarks" , "They're not heard by everybody" .)
