This add live album art pulling via Discogs (provided CBC has a playlog. Most effective on CBC Music, not CBC Radio One).
If it cannot match artist AND title for the album, it will return nothing. I was getting way too many false positives searching only the album name.
You'll need to create a Discogs account and create an API Key, which you can fill in on line 10 of now_playing.py (for now. Proper config coming).
