How to download music from computer to iPhone?

Ok so I have no Internet on my computer ATM, but I have tons of music on my computer that I downloaded onto it,&i was wondering if their is a way to download those songs to my iphone without using Internet

Unfortunately you need to "sync" the PC and your iPhone. Don't overload your phone, I would get an iPod, well I did? You can only try and see. I put iTunes on my PC and synced it to my iPod, but I have internet and it used my iCloud as a backup?

I do not currently own an IPhone, but I think you should use your USB cord to transfer all your songs.
