How to get music from my laptop onto my iPhone?

I originally set up my iPhone and iTunes account through my other computer and now I want to be able to share my library and add music to my iPhone from my laptop. I have turned on the home sharing and have allowed the laptop to be one of the computers to be able to access the music on my phone and it still didn't work. I did this same process with my iPod and it worked perfectly but it still won't work with my iPhone… What do I do?

Itunes

You will have to use a USB or external hard drive to copy your music from the other computer to your laptop. Then sync the library to the laptop.

  • Transferring Music From My Laptop Onto My iPhone? Okay so there's this song that I really like. It's a cover to a song, so they don't have it on iTunes. My phone is an iPhone, but my laptop is not by Apple. I read on one answer that I need iTunes for that on my laptop, but I didn't download it. What I did already though, is I used a YouTube audio converter and downloaded the song onto my laptop, but I need to get in on my phone. How do I do this?
  • Put music onto iPhone on someone else's laptop? I'm currently overseas for the year and have my iPhone with me, but not my laptop, and I would like to add some of the music from my friend's laptop onto my phone. Is there a way for me to obtain the songs I want (in a playlist) without all of her music (and apps and photos etc) transferring to my phone, or my music transferring to hers? A step by step tutorial would be so useful as I can't find one that explains it clearly!
  • How to transfer music onto my iPhone from my laptop? I have a Windows 7 laptop, and I've already tried downloading iTunes but it doesn't work at all on my laptop, and I've even tried downloading older versions of it and it still doesn't load. Is there any other way I can get music onto my iPhone 5c without iTunes?!
  • How to sync music from my iphone onto my laptop? Somehow my music all got deleted from my itunes and I wanna put it back. But all it says when I plug it in to my laptop I can only sync the music from my computer onto my phone - and I wanna do the opposite of that. I hope this makes as much sense as I think it does.
