How to get music on my iPhone WITHOUT using iCloud?

I have 100 some free gb of space on my iPhone and I want to download all of my music onto my iPhone without it being over iCloud. The reason is because I don't want to always be streaming my music because 1) it uses my data like crazy and 2) it buffers like crazy. Please help me out! I know it shouldn't be that hard

You could just download all you want to iTunes & then sync that to your iPhone. I suggest using a computer to do this though. That's it.
