Record part of hit EMI series (7)
I believe the answer is:
itemise
'record' is the definition.
('record'->'itemize' is in my internal thesaurus and 'ize'->'ise')
'part of hit emi series' is the wordplay.
'part of' says the answer is hidden in the clue.
'ITEMISE' can be found hidden inside 'hit emi series'.
(Other definitions for itemise that I've seen before include "Formulate a list" , "Enumerate" , "List, state each object" , "List in detail" , "List out singly" .)
