Where do I find the option "Only sync checked songs and media". I can't find it in the preferences or drop down menu of iTunes on my computer. Hopefully I'm just overlooking it!SikShift is right. If you don't want those on your phone any longer, uncheck the particular songs you want removed. You must also be sure to check the option "Only sync checked songs and media". You can highlight multiple songs at once and choose to either "Check or Uncheck selection" to make it a bit easier.
Lol. Just be careful what you delete though, don't just assume they are all duplicates. Some songs have the same title etc or you might have differet versions of the same song. So just check before you select all and hit the delete button.I also needed to do this and hadn't figured out this way. Thanks!
The sync or apply button will not show up unless u make a change in the music section. So if you are trying to delete all songs or a certain playlist uncheck that box and it will then show the sync or apply button.Kadelic, I appreciate the concise answer. But I had a problem ... I do not see a box that says "Sync Music". The button that shows up for syncing is labeled "Autofill".
