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!
Go into your music library in itunes and right-click on the music you want to delete.

If this happens, then the time when you will sync your iPod to iTunes, all your songs on your iPod will be deleted. If you want to prevent this from happening, connect your iPod to your Mac or PC, iTunes will open with a warning message, just refuse to format your iPod, then download a software called 'Touch Copy'. There is a free trial version I think. Follow the steps, and all your iPod contents will be uploaded to your mac or pc. Just add everything to iTunes again and sync safely. Thanks.
