'pop star' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'adjust audio fast' is the wordplay.
'adjust audio' becomes 'taylor' (I can't explain this - if you can you should believe this answer much more).
'fast' becomes 'swift' (similar in meaning).
'taylor'+'swift'='TAYLOR SWIFT'

'to' is the link.
