Which app can I use to download free music off?

I've gotten a new iPhone 5S and I've been on the app store to try and download a free music download app that was on my iPhone 5. However all I'm seeing is stuff like "free music download for soundcloud". I just want a free music download app where it allows you to browse websites on it and download music on it. Please if you do find an app like that then please let me know below.

Just buy a gift card and use that

If you bought the app previously it would be under your Purchased section

ITube is good but it doesn't "download" music per se. It connects to YouTube and saves the whole video once it's been fully loaded.

I do have an app that downloads music as well but it's been removed from the store, so there could be other apps out there.
