This one has only one variable: "song" and does not have numbers involved.
Why deal with numbers when you can deal with the name of the songs themselves.
to startup
make "song "beach
end
to change_songs
if :song = "beach [
set :song "on? "false
make "song "forest
set :song "on? "true
stop
]
if :song = "forest [
set :song "on? "false
make "song "happy
set :song "on? "true
stop
]
if :song = "happy [
set :song "on? "false
make "song "beach
set :song "on? "true
stop
]
end

To save an attachment to your computer, PC users should right-click (Mac users, click and hold the mouse button) on the link and then choose 'save target as' from the pop-up menu. A window will then pop up in which you can choose a location for the file.
