IPhone sync won't get past Step 1?

I plug my iPhone in and it acts like it's syncing. It won't finish though. I will cancel the sync and it will just say "Canceling sync" and will continue to stay that way. I went through All of my music and sorted out what I wanted to put on my iPhone. I clicked the apply button and it stays stuck at Step 1- Waiting for Sync to Start. I have no clue what to do to get it to finish the sync. Any ideas? Also, in my current music on my iPhone there's a lot of faded music is there, but I can't click it or listen to it. Any ideas how to get those off?
