Pushes stream with song’s intro at the end (5)
I believe the answer is:
urges
'pushes' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for urges that I've seen before include "Compulsions" , "Drives" , "Advocates strongly" , "Persuades to do something" , "Eggs on" .)
