Applescript update iTunes stream title without obstructing rest of script -

i using code below current itunes stream title. works great. need be, script updates every time when itunes stream title changes, variable title updates well.

repeat tell application "itunes" set title current stream title end tell delay 2 end repeat 

however, because of ongoing "repeat" function, rest of script not execute. know of way still variable title updated when itunes changes title, not obstruct rest of script? if sort of runs in background? thank you!

a solution, use handler (handlers known functions, subroutines, or methods). put rest of script in handler, call handler loop.

like :

set oldtitle "" repeat     set t ""     try         tell application "itunes" set t current stream title     end try     if t not "" , t not oldtitle -- title changed         set oldtitle t         dosomething(t) -- call handler      end if     delay 3 end repeat  on dosomething(title)     -- put rest of script here end dosomething
