What are the best ways to download free music onto your iPhone?

I just bought the iPhone 6 and I need a new way to download music. I download music all the time that I don't want to spend all my money on iTunes.

Jail break it then get it on uTorrent

Using your computer. Then copying to your phone.

Honestly you iPhone owners are making life hard on yourselves reinventing the wheel. You insist on downloading directly to your phones not bothering to learn how to save music from your phones. Then your phones get lost or stolen or need to be restored and replaced. And since you never learned how to copy from your phones you never learned how to save your music.
