Fascinating song singer composed (10)

I believe the answer is:

engrossing

'fascinating' is the definition.
(synonyms)

'song singer composed' is the wordplay.
'composed' indicates an anagram.
'song'+'singer'='songsinger'
'songsinger' is an anagram of 'ENGROSSING'.

(Another definition for engrossing that I've seen is " Absorbing the attention".)

I've seen this clue in The Everyman puzzle in The Observer.
