If, like myself, you have many different genres of music on itunes, but are sick or hearing only 1 or 2 of ur largest genres all the time, this playlist creates an even mix of all your genres
1st, create one playlist for each genre which would look something as follows:
genre -> is -> rock
last played -> is not in the last -> 8 weeks
my rating -> is greater than -> 2 stars
limit to 20 songs
live updating
i name all of these Z-G-Rock; the Z to bring it to the bottom, the G to signify which master playlist this relates to (genre) and rock to tell me more info.
after making one of these for each genre, sumtimes with slight modifications depending on the number of songs you may have for that genre, i created the master playlist from all of these like this:
Match Any of the following conditions
Playlist -> is -> Z-G-Rock
Playlist -> is -> Z-G-Techno
Playlist -> is -> Acid Jazz
Playlist -> is -> Funk
