You should put the mp3 file in the same location as the python file and remame mp3 to "input", or type in the mp3's name when it asks you for it, in order for it to work (not sure if you asked for this explanation)
You also need to make sure you go to the real directory, since some software could run the python file in a seperate location, where your mp3 isnt there
It automatically converts the mp3 to pcm data that works in the composer, so you dont put in a ready to go pcm data, you just put in a mp3
I have also made a version 3, where it tries to use less data or "compress", you could tell me if you found a bug
