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.

Do the monthly payments of an iPhone 5s and a 5c differ?

So would the monthly payments be diffrent if I was to get the same exact plan?

I would probably get unlimited texting and our family plan already has a certain amount of call minutes so I could use those…

Non-expensive iPhone 5s phone case?

I have a case on my iPhone 5s right now but when I take pictures with both the front and back camera, my phone case gets in the way and changes the color of my picture and makes it look bad.

Links are appreciated!

Is it possible to upgrade iPhone 4 memory?

Now before anyone starts to say no straight away let me give you some details because I'm no idiot.

I know there isn't a memory unit available to swap out on its own without de soldering from the logic board and even then there isn't much chance a new memory unit would work… What if I took my logic card (8gb) and put a lets say 32gb one in… Would it still work? Or will it just break my phone?
