Replying to Itunes Help

I just downloaded sone songs off of limewire and just dragged them from limewire into my itunes. When i did this, those little '!' things popped up to the left of most of my songs. When i try to play the songs with the '!' things, it says that i have to locare the origional file because itunes cat locate it. I have all the files and i could just go throught and manually do all of them, but when i locate one song's file, the song right under that one gets a '!' thing. Is there any way to fix this without manually going thought and doing every song?
