itunes loop

im trying to make an applescript look with itunes so that the volume never goes off, both on the cpu and itunes, and so that a single track plays constantly. also, if itunes is exited out of, it reopens. but therein lies the problem. when it does that, i always get an error returned saying "iTunes got an error: Connection is invalid." number -609. anyone know a scipt i can use to get past this, or heck, even can write the above?
