The first one, is called 'Missing Data', and has these rules:

* Match any:


* Album contains 'Unknown'


* Album contains 'Unidentified'


* Artist contains 'Unknown'


* Artist contains 'Unidentified'


* Artist is 'Various'


* Artist is ''


* Name contains 'Track'


* Name contains 'Track0'


* Name contains 'Track1'

Live updating, no limits.

Optionally, I also created a static playlist called 'Valid Missing Data' where I placed all the tracks that match the above criteria but are not in fact missing any data. Then you can create another smart playlist called simply 'Missing Data' which has the following rules:

* Match ALL


* Playlist is "All Missing Data"


* Playlist is not "Movies" (optional)


* Podcast is false


* Playlist is not "Valid Missing data"


* Match only checked items


* Live updating

That should create a list of tracks you need to look through and fix up!

The next playlist, I use in conjuction with the Party Shuffle feature. I set a few playlists up. The first one is called 'Other Video', that contains all the video tracks in my database that are not music videos:

* Match ANY


* Video Kind is Movie


* Video Kind is TV Show

Then, I have a playlist called 'All Unrated':

* Match ALL


* Rating is 0


* Podcast is false


* Playlist is not 'Other Videos'


* Match only checked items


* Live updating

Finally, in the party shuffle playlist, I set the source: as 'All Unrated', Display: 5 recently played songs, and 15 upcoming songs.

This way, I can play through my party shuffle which will only take unrated tracks. As I rate a track, it's immediately removed from the 'All Unrated' playlist, but it doesn't stop playing because it's in the party shuffle playlist. At some point, all songs will be rated :)
