Got new ipod mini!!!

But i want to know how i can take off the checkmarks on each of my tracks. I have 20gigs plus of music and a 6 gig ipod. i want to unselect everything w/o having to do it manually. advice?

Click the first song in the list in order to highlight it, hold down the Shift key, then click the last song in the list. Then Crtl-click on the highlighted song, then select "Uncheck Selection".
