I have this Rock & Pop play list that I listen to from time to time. It’s a “smart” playlist and the criteria of the playlist are such that it eliminates anything that isn’t in the rock or pop domain of music. This leaves me with about 2,400 songs in the play list. On some days, like today, I spend much of the day listening to this playlist in shuffle mode. Today I listened 60 songs on the list. I want to continue to do this tomorrow.
On the of the problems with doing that, though, is that if I start over tomorrow, I’m likely to hear some of the same songs as I did today and I don’t want to do that. I don’t want to hear the same song again for at least 24 hours. On the train home, I wondered if I could come up with something that would solve this problem for me. I just did.
I added one additional criteria to my smart play list:
[Last Played] [Is not in the last]  [days]
This means that once I sync up my iPod tonight, I can play the list again tomorrow and I won’t hear any songs that have already been played in the last 24 hours. Pretty cool, eh?
