Free Music Download on iPhone 4s?

I have no music on my iPhone 4s, and I'm a music fanatic. Is there any app on the AppStore that I can download and have free music without Wi-Fi? Or can someone please tell me how to jailbreak my phone so I can get free music?

There's no such app on the AppStore last time I checked, and if there's, it's not that great. If you have a computer, download the latest version of iTunes on it. Go into google and search "mp3skull.com". Once you're there, search for the music you want and right click on the download button and click "save as". Rename the file to whatever you want and it'll download. Once it's done, click on it. It should open in iTunes. I suggest you create a playlist and add all the songs you want on your phone. Now connect your iPhone to your computer and go to the music area. Now click the "sync only selected songs" click that playlist you created.
Or type in "how to transfer music with iTunes to iPhone" in YouTube. Also search how to to jailbreak [firmware] [iPhone type]. So example: how to jailbreak iOS 7.0.4 iPhone 5s. To know the firmware, go to settings, general, about. Hope I helped.
