Records 1001 new tunes (7)
I believe the answer is:
minutes
'records' is the definition.
(minute is a kind of record)
'1001 new tunes' is the wordplay.
'm00m' becomes 'mi' (I've seen this in other clues).
'new' is an anagram indicator.
'tunes' anagrammed gives 'nutes'.
'mi'+'nutes'='MINUTES'
(Other definitions for minutes that I've seen before include "Written account of a meeting" , "summary" , "Records" , "Record of a meeting" , "Recorded notes of a meeting" .)
