Popular song to remain at the top of Indian chart finally (4,2)
I believe the answer is:
beat it
'popular song' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'remain at the top of indian chart finally' is the wordplay.
'remain' becomes 'be' (I've seen this in other clues).
'the top of' suggests taking the first letters.
'finally' says to take the final letters.
The first letter of 'indian' is 'i'.
The final letter of 'chart' is 't'.
'be'+'at'+'i'+'t'='BEAT IT'
'to' is the link.
Can you help me to learn more?
(Other definitions for beat it that I've seen before include "Scram, take a powder" , "Sling your hook!" , "Make off hastily" , "Scram, get lost" , "Slang order to go away, get lost" .)
