Ok, so I was on the computer a little too late last night and I accidentally deleted 1700 songs off itunes. I deleted all of my most recently add music completely using the option delete key on a mac in the playlist. I was only trying to delete 7 songs but I guess i didnt realize i had the whole playlist selected. So, there went the 1700 songs too my trash. Luckily i recognized it before i emptied the trash and i imported them back into itunes. The problem I have is all the playlists that have those songs that i erased are no longer there. My ipod is setup to sync with a few playlists. So, what i am wanting to do is to have itunes update itunes playlist info so that it contains all the original songs. I don't want it to delete the songs off my ipod. Is there a way to do this? Basically i don't want to go back and add all the songs to the playlist again and sync it, i'd rather use the information from my ipod to pull the music back into the playlist.
