What I want to do is simply
mp3 = read_mp3(mp3_filename) audio_left = mp3.audio_channels[0] where audio_left will contain raw PCM audio data.
I was looking at Play a Sound with Python, but most of the suggested modules are not ported to Python 3 yet. If possible I'd like to avoid having to install a fully-fledged game dev library.
I'm a complete Python beginner, so I'd like to start off using Python 3.

Conclusion: Playing and Recording Sound in Python You are now able to: Play a large range of audio formats, including WAV, MP3 and NumPy arrays. Record audio from your microphone to a NumPy or Python array.
open() This function opens a file to read/write audio data. The function needs two parameters - first the file name and second the mode. The mode can be 'wb' for writing audio data or 'rb' for reading.
All you have to do is double-click on the MP3 file you want to listen to and by default, your audio player will open the file and start playing. If, however, you prefer a different audio player than either of those, changing the association of a file is a simple process on either Windows or macOS.
You could use librosa:
import librosa y, sr = librosa.load('your_file.mp3') Further information: https://github.com/librosa/librosa

To make it easier I'd convert with some tools mp3 to wav, either:
$ ffmpeg -i foo.mp3 -vn -acodec pcm_s16le -ac 1 -ar 44100 -f wav foo.wav or $ mpg123 -w foo.wav foo.mp3 Then read the WAV with one of the python WAV libraries. I'd recommend PySoundFile because it works with most generated WAV correctly and installed without issue (as opposed to scikits.audiolab).
Note: Even though scipy.io.wavfile.read() gave me a "WavFileWarning: Unfamiliar format bytes" warning, it also loaded the file properly.
