Free music app that doesn't use data?

Is there an iPhone app that allows me to listen to free music without using any of my data? I'm going on a trip tomorrow and I'm tired of listening to the same music again and again. I have the 10 GB plan for my iPhone 5s.

That's impossible, ANY streaming or downloading uses data, heck even browsing the internet or using Facebook uses data. Only way to listen to music without consuming data is to download the songs onto your computer and sync using iTunes.

Music can't just magically appear to on your phone, apps are not like magic beans, LOL.

I used to have a music app that didn't use any of my cellular data. So they are out there, finding them is what is hard.

There's some but they are really hard to find. I had it on my iPhone 6 plus, but it broke. So when I got a new One I couldn't find it anymore
