A script I made to parse files out of WMP playlists so I could move them into a new player.

parse-json-playlist.py

import json
from shutil import copyfile
import os

fil = open("playlist.json")
jstring = json.loads(fil.read())
medialist = jstring['media']
os.mkdir("newplaylist")
for item in medialist:
    try:
        newfil = item['_src']
    except:
        continue
    print newfil
    copyfile(newfil, 'newplaylist/' + newfil[newfil.rfind("\\"):])

Steps to use:

1. Create a WMP playlist and dump all of your Groove music songs into it.
2. Extract the tags ONLY from the wpl file and convert them to JSON.
3. dump the json into a playlist.json next to the script and run the script
4. Drop your files into your new media player or playlist.

This script will not overwrite its old folder or files. Be sure to delete the "newplaylist" directory if you're running it multiple times!

Pardon the hardcoding, I did this late at night.
