If they did not go into the Trash they may be in the Music folder within the iTunes Music folder within the iTunes folder in your Music section.
Uniinstall Itunes (start menu, control panel, add remove programs), then reinstall itunes. When installing Itunes it will ask if you would like to search (or import depending on the itunes version) music from your pc. select yes. This should solve your problem.
The music files should still be in your "My Music" folder.
If you are updating the iTunes software to the latest version your music library will not be affected.
Only the iTunes software is updated your music library will not be touched by the update.
Why does iTunes lose your music library?If you have put any new music on your iPod lately, your computer could have synced your iPod and deleted all of the music.
Go into your music library in itunes and right-click on the music you want to delete. The window that pops up should have a delete option, click on it and the music will be deleted from your library and the next time you sync your ipod, the music will be deleted from there too. (I'm not sure what other versions of itunes this works with, but i know it works with itunes 10.)
If the song is permanently deleted from every source you have, you will just have to pay for it again.
Do you mean you deleted them from your Itunes? If so than go to:# My Music>Itunes>Itunes playlist>(than you go to the Artist of the song and open it, open the album, than delete the song that you want to delete(you will have to do this 300 times though(if you had only 300 songs on Itunes to begin with and deleted every single one than right click in the folder: My Music>Itunes>Itunes playlist; and then click Select All and then Delete.) If you have an IPOD Touch or IPone than you might have been able to delete them straight from the phone, if so follow the same rules but delete those same songs from your ITunes playlist also.Anyways, Why would you want to delete 300 songs from ITunes? That is about $325 worth!
I presume your talking about an ipod? If you've deleted them from your ipod, you just need to connect it to itunes and put all your music back on. If you've somehow managed to delete them from itunes, you will need to go back to the itunes store and redownload ALL your songs (if you have trouble remembering all your songs, just go to your inbox and check your itunes receipts) if you downloaded from a p2p file sharing network (e.g limewire, frostwire) you can just go up to library>downloaded then drag all your songs from there into itunes then onto your ipod.
download itunes go into the music store and sign in using the email and password from when you registered
You must drag it back onto the iPod via iTunes when your iPod is plugged into the computer.
No, your music on your computer will be safe. However, bscause iTunes only allows an iPod to be synced with one music library at a time, the music won't be able to be synced to another computer.
