Operation inverted current total held by computer in numbers? (3,5)
I believe the answer is:
pop music
'computer in numbers?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'operation inverted current total held' is the wordplay.
I cannot quite see how this works, but
'operation' could be 'op' and 'op' is located in the answer.
'current' could be 'i' (symbol for electric current) and 'i' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for pop music that I've seen before include "Hit parade genre" , "Entertainment form" , "Young people's songs" , "Genre of entertainment" .)
