Spotify. Download your playlist and use it to listen to music wherever you are.

Pandora… You don't need Wi-Fi I always go out of Wi-Fi range at some point when I'm on campus waiting for my English 102 class

The stock music app lets you play music offline. That's what I did for many years when I used iOS devices. Of course you need to load your own music through the iTunes app or the computer program.

If you're wanting to obtain free music, that is usually illegal.

Your stock Music app.

You either have to have the music on the device or stream it through an internet connection. That's how it is for all phones. They wouldn't have any phone that could magically play music that's not on it through no connection.

You ALWAYS need Wi-Fi.

You don't need Wi-Fi to LISTEN to music. You need Wi-Fi to DOWNLOAD music.
Rumor has it that Apple has such a music app called "iTunes".
