How to download music to iphone 5c?

I don't want to buy it from itunes! I couldn't afford to is there any way I can get free music?

You can actually win free iTunes gift cards, and hence get music for free from the iTunes store. This is probably one of the very few legal ways to do so.

First of all, on your iPhone, iPad or iPod Touch, go to https://welcome.freemyapps.com/getstarted.html?44a4e6fc
This site is called FreeMyApps. You'll have to download apps, and in return, you'll earn points. You can then use these points to redeem iTunes Gift Cards.

Proof that this site really works:
1. From personal use. I've already earned $230 worth of gift cards.

-----XJPRD534QMY5XJMD ($10 Card)
-----XD4T7GCTCM26RW7C ($10 Card)
-----XFWWRDM5MHW72HJ7 ($10 Card)
Note: I already used these codes. This is just proof.

2. They posted about it on iJailbreak.com (a credible and well known site about Apple devices (http://www.ijailbreak.com/applications/download-free-ios-apps-from-freemyapps).

Here is how I download free music to my iPhone:

1. Find free music website, download any music to my pc first.
2. Then connect my iPhone with pc.
3. With the help of Syncios, transfer music from pc to my iPhone.

Syncios is totally free, you may have a try. If you still want to use iTunes, you can simply use Syncios to add music to your iTunes library, and sync your iPhone with iTunes.
