applescript – Delete iTunes song with partial name from the clipboard

I'm trying to delete a track from a playlist in iTunes using only a partial name from the clipboard. He keeps giving me an error saying he can not find the clue. I'm pretty new to AppleScript, so I probably did something wrong. Any help would be appreciated! This is what I have until now.

set iTunesdelete to the clipboard

Tell the application "iTunes"
delete track (track whose name contains iTunesdelete) from the user's playlist "Current project AAA"
tell him at the end

Alternately I have this, which does not give an error, but it does not do anything either.

set iTunesdelete to the clipboard

in deleteTrack (iTunesdelete)
Tell the application "iTunes"
configure the path in (file tracks whose name begins with iTunesdelete) from the user's playlist "Current AAA Project"
Set songFile to the location of the track.
delete the Track
tell him at the end
Tell the "Finder" application to remove songFile
end deletetrack

Tell the application "iTunes"
set the result in (file tracks whose name starts with iTunesdelete)
repeat with t in the result
my deletetrack
end of repetition
tell him at the end
finish
