Expression of surprise about recording getting top position? (5)
I believe the answer is:
alpha
'top position?' is the definition.
'alpha' can be an answer for 'top' (I've seen this before). I am not sure about the 'position?' bit.
'expression of surprise about recording' is the wordplay.
'expression of surprise' becomes 'aha' (I've seen this before).
'about' indicates putting letters inside.
'recording' becomes 'lp' (LP is an example).
'aha' going around 'lp' is 'ALPHA'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for alpha that I've seen before include "First letter of the Greek alphabet" , "piece of Greek writing" , "leader in Athens, originally" , "starter" , "First-rate" .)
