I have 887 songs in my iTunes library, and last night I deleted some of them right off my iPod touch, 4th generation. At the end I got 769, and in the morning I connected my iPod to iTunes, I did some changes that had nothing to do with my music, because they were fine, but then I clicked sync and again, the songs I deleted from my Ipod were again in my iPod! how do I sync my iPod to actually "update" my iTunes library, I don't want to delete the music again or do I need to delete the same songs from my iTunes library too?
You need to tell iTunes not to sync those songs.
- Uncheck the songs you do not want to sync in the iTunes "Music" list.
- Check "Sync only checked songs and Videos" in the options for the device.
