The Pokémon Company released a new app today called the Pokémon Jukebox which allows you to listen to three songs as much as you want each day for free, you can also play with Pokémon sound effects. Other than the three free songs you can listen to, there's options to purchase the game music on the app as well.

You can download Pokémon Jukebox for your Android device over at the Google Play Store.
