Blurt tune out, getting unsettled (9)
I believe the answer is:
turbulent
'unsettled' is the definition.
(thesaurus)
'blurt tune out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'blurt'+'tune'='blurttune'
'blurttune' anagrammed gives 'TURBULENT'.
'getting' is the link.
(Other definitions for turbulent that I've seen before include "Tempestuous" , "Stormy" , "Wild, unruly" , "raging" , "like Becket?" .)
