Perhaps rock and roll CD in US came out (5,5)

I believe the answer is:

dance music

'perhaps rock and roll' is the definition.

'cd in us came out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'cd'+'in'+'us'+'came'='cdinuscame'
'cdinuscame' is an anagram of 'DANCE-MUSIC'.

(Another definition for dance music that I've seen is " Ball sounds".)

I've seen this clue in The Guardian.
