  Hi Daniel!
  Thanks for your answer, Its belongs to the second part of my question- 
"other clever solutions", but the solution is conncected with recursion, and I 
want more simple solution, Is there a way to do it like I wrote (with 
variables) and not to click twice on the turtle, because my suggestion is 
working, but you have to click twice on the turtle.
                                             Thanks, Zehava

I had to separate the launching of the music from the action of
the turtle because when the turtle was cancelling the music it 
was also cancelling it's own actions (weird behaviour). 
So here is a work-around:

to startup
make "songs [happy forest beach]
make "current "xxxxxxx
when [not :current = first :songs] [
cancel :current
make "current first :songs
launch :current
]
end

to change_songs_1
make "songs lput first :songs butfirst :songs
show :songs
end
