What music app can I get for iPhone?

I have an iPhone 5c and I used to have the itube app but I accidentally deleted it and I didn't have it backed up on my computer and it is no longer on the App Store! Is there any other music apps I can download that will word without Wi-Fi when I'm out?

The guys at Apple changed their policies and stuff so that you can only listen to remixes and not the real song without buying it. If you download VShare (look it up on your IPhone) you can find lots of free apps and use the search bar to find your old app, or an upgrade! They all work just like the old one and will work on the go. Happy Listening!
