Playing only new material (5)

Ross

I believe the answer is:

nylon

'material' is the definition.
(nylon is a kind of material)

'playing only new' is the wordplay.
'playing' is an anagram indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'only' with letters rearranged gives 'nylo'.
'nylo'+'n'='NYLON'

(Other definitions for nylon that I've seen before include "Unaccompanied part song" , "The first synthetic fibre" , "Fibrous material" , "Tough synthetic material" , "Synthetic cloth" .)

I've seen this clue in The Sun.
