Don't do that.

But that's not "using your existing... functional-programming thingy"
mentioned above.
mp3_files = sorted(os.path.join(mp3_subdir, x) for x in
filter(lambda f: f.lower().endswith(".mp3"), os.listdir(mp3_subdir)))
There's also glob.glob() that would probably make the above simpler.
https://docs.python.org/2/library/glob.html
mp3_files = sorted(glob.glob(mp3_subdir + '/*.[Mm][Pp]3'))
mpg321 sees the literal string `*.mp3' and tries to open it. If it
exists, it would play it.
A raw `*.mp3' in the source don't mean those filenames to Python as it
doesn't glob strings like a shell. That's why you're doing listdir(),
etc.
I think part of the problem here is you're trying to write a program to
meet your needs in Python, not trying to learn Python so you can then
write a program to meet your needs. :-)
Cheers, Ralph.
