Hey guys, for the past few days I have been experiencing issues with syncing songs to my 5S. I keep a lot of music on my macbook but have a playlist for just the songs I sync to my iPhone. Lately, the songs that I add to that playlist don't sync to my phone and when I click my iPhone tab in iTunes and scroll through the music list, it has a dotted-circle by the songs that won't sync. I've tried deleting the songs and re-adding them but it still doesn't work. My Mac, iTunes, and iPhone are all running the same software. Please help-I got a 64GB 5S because I am constantly adding music and now I can't do it. Thank you!!
