Turns up on The Hill for the music and is likely to repeat everything you say (6)
I believe the answer is:
parrot
'the music and is likely to repeat everything you say' is the definition.
I can't judge whether this definition defines the answer.
'turns up on the hill' is the wordplay.
'turns' says the letters should be written backwards.
'up' becomes 'rap' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' is a charade indicator (letters next to each other).
'the hill' becomes 'tor' (tor is a kind of hill).
'rap' after 'tor' is 'torrap'.
'torrap' in reverse letter order is 'PARROT'.
'for' is the link.
Can you help me to learn more?
(Other definitions for parrot that I've seen before include "Repeat automatically" , "Ape" , "Squawking bird" , "One repeating" , "Vividly coloured bird" .)
