Free music app on App Store for iPhone 4?

So I have an iPhone 4. And I just got it replaced with another iPhone 4 Cuz my screen smashed but anyway last time on my phone I had spotify. It used up to much data. We don't have Wi-Fi so I only used it on 3G which takes up a lot I data. It took up so much it would turn offfm data connection until the billing cycle restarted. Is there any free music app I could use and not use so much data? Or download music without iTunes?

I use:
APPS
*8tracks
*Songza
*TuneIn radio
*Pandora
DOWNLOADS
*mp3 music downloader
*free music download-mp3 downloader

  • Why does the App Store want to know my billing information if the app is free? On my iPhone 4s, I try to download an app from the app store, first it'll ask for my password which is normal, and I put it all in correct but then it'll redirect me to my billing information/payment method and ask me to fill it out. I can't remember what my prepaid security number is because I haven't had it in so long so I can't do it. But the apps I try to download are completely free so I don't understand why this would happen. Is there anyway to fix this?
  • What is a good IPhone music app with free music? I had the perfect app once but I got a new phone and it got deleted. I have been searching forever but with no luck. The app I'm looking for is a free app through which you can download musics for free and straight from the app without all that internet downloading stuff. These are the characteristics in simple form: 1. Free music app 2. Has in app downloads (do not have to search the web) 3. Preferably has a sorting system like playlists
  • What is a good app from the App Store to download/get free music? I have an iPhone5, and I have tried some different apps and nothing is really cutting it for me. I refuse to pay for the songs on iTunes, because I just don't agree with the prices. If you have an app you use on your iPod/iPhone/iPad or anything from the app store please reply!
