I'm not exactly sure how to word what I need done. The hard drive crashed on my iMac, and I had to have it replaced. Luckily, I had all my iTunes library saved on an external drive, so I didn't actually lose anything. However, I had it set to where it would only sync the checked songs, and now that I've had to reload my iTunes library, it lost the checked songs. Is there a way I can somehow have my iPhone communicate to iTunes what songs should be synced? Does that even make sense?
