There is a speaker and two buttons on your Circuit Playground Bluefruit, and CircuitPython includes the ability to play MP3 files. This example plays a different MP3 for each button pressed. Be aware, the speaker is small, so you will not get high quality MP3 playback using the built-in speaker.
Try pressing each button individually to hear a different MP3 file.
