You print to the serial console Playing: and the name of the file currently playing. Then, for each file in the mp3files list, you open the file in the decoder, use the audio object to play the decoded MP3 file. This is necessary to be able to reuse the decoder object multiple times later. Then, you open the first MP3 file in the list, and use it to construct the decoder object. There are only two in this list, but you could add as many as you like to the list, copy the associated files to your CIRCUITPY drive, and the code will play them each consecutively. This time, however, you create a list of mp3files, with each file name as a string, including the. The code starts out the same, with the same imports and audio setup.
