I'm turning up original tunes for record (7)
I believe the answer is:
minutes
'record' is the definition.
(I've seen this before)
'i'm turning up original tunes' is the wordplay.
'i'm' becomes 'im' (**).
'turning up' says the letters should be written backwards.
'original' indicates an anagram.
'im' in reverse letter order is 'mi'.
'tunes' with letters rearranged gives 'nutes'.
'mi'+'nutes'='MINUTES'
'for' is the link.
(Other definitions for minutes that I've seen before include "Record of a meeting's decisions" , "Units of time" , "Written account of a meeting" , "Recorded notes of a meeting" , "Record of a meeting" .)
