ok, so my computer had barely any space on it, so i was deleting as many things as possible. By accident, i deleted my itunes library(1898 songs)I didn't delete it from itunes. I deleted it from applications, then itunes drop down menu, then al these artists. after that, i emptied my trash.... so i have nothing. now i only have one song on my itunes, which is the one i was listening to when my songs got deleted. But now, when i go on itunes, it looks like i have all my songs, except there are small little exclamation points next to each song. When i click a song to play, the song cant be found. I NEED HELP!
