ITunes songs syncing to iPhone?

I was having trouble making all my songs on my phone available offline, like they are on my computer. I plugged my phone into my computer and had everything sync, but one song won't sync onto my phone. Why won't just this one song show up on my iPhone? I bought it through iTunes!

"After about 2 months scrolling through these forums I finally found a fix for this problem! I simply turned off the "Sync Music" checkbox on the "Music" tab in the page for the device on iTunes. I then checked the "Manually manage music and videos" box at the bottom of the device summary page, selected all of my music in my library and simply dragged it all to the device and the music is now all playable on my iPhone (with no duplicates, despite dragging all of my music onto the device). This was such an easy and annoyingly simple fix so hope it works for you too!" ~some guy on apple forums

  • Will syncing my new iPhone remove my songs on iTunes? Hi, I just got a new phone and I'm confused! I've got an iPod Touch will over hundreds of songs on my iTunes. If I plug my new iPhone in to the computer, will I be to transfer my iTunes songs on to my phone without it deleting anything? Will this make a difference when I plug my iPod into the computer? Haha I don't know much about phones tbh!
  • Why aren't my songs from iTunes syncing to my iPhone? I have 1365 songs in my iTunes library which I can play. But only 1260 songs are transferring over to my iPhone. I just got a replacement iPhone about 4 days ago so I'm not sure if that has to do with anything?
  • Why aren't all my songs syncing onto my iPhone? I just got my iPhone last week, and after I synced all my songs (590 of them) to my computer, I tried to sync them onto my iPhone. However, only 345 of them are syncing. In iTunes the box next to "Sync Music" and "Entire Music Library" is checked. Down at the bottom the bar that shows how much music, apps, photos, etc.shows that I have 590 songs, but once I click "Apply" it syncs, but the bar reduces to only 345 songs!
  • Syncing iPhone songs onto iTunes? Okay so what I want to do is make ringtones on my iPhone 4s. But in order to do that I have to sync my iPhone to iTunes. Which I haven't done yet with my phone. I have 60 songs that i bought on itunes store on my phone but I don't want to lose them. And i heard if I sync my phone to the computer that it will wipe everything out of it? So is there any way to sync the songs and all the apps and media from my phone onto itunes on my laptop?
