Songs -- they may make you feel nothing (7)
I believe the answer is:
numbers
'songs' is the definition.
(as in musical numbers)
'they may make you feel nothing' is the wordplay.
I cannot quite understand how this works, but
'you' could be 'u' (homophones) and 'u' is found within the answer.
'feel' could be 'be' and 'be' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for numbers that I've seen before include "They subdue the pain" , "Biblical book - anaesthetics" , "Figures, digits" , "Old Testament book -- narcotics?" , "OT Book 4" .)
