I have an iPhone 5. It's 64 gb and I've always been able to sync all of my music to it. Now, since yesterday, it shows 7.47 gb of "other" in iTunes. I have no idea where it came from. It wasn't there yesterday. How do I get rid of it, so I can put my music back on my phone? I just synced again and now it's up to 7.51 gb!
