stupid question regarding iTunes

[The Red Menace]

I was screwing around with my music and somehow unchecked all of my songs. How do I go back and check them again?:confused:

[yippy]

Select all of the songs you want to check. Right-click or control click on one of the selected songs. Choose the "Check Selection" option. Done!

shift-clicking one song sets them all to whatever you set that song to. Shift-clicking an unchecked song sets everything in the current playlist to checked, and vice-versa.
