Extract from 'Batman' theme song (6)

I believe the answer is:

anthem

'song' is the definition.
(anthem is a kind of song)

'extract from batman theme' is the wordplay.
'extract from' says the answer is hidden in the clue (I've seen this in other clues).
'ANTHEM' can be found hidden inside 'batman theme'.

(Other definitions for anthem that I've seen before include "Church choral piece" , "Song of praise or loyalty" , "National tune" , "Uplifting music" , "The man for a patriotic song" .)

I've seen this clue in The Telegraph.
