I have often wondered why apple chose to have a playlist called '90's music' in itunes. The others seem to follow a pattern like its helpful to be able to see all the recent tunes u added and 'recently played' so u have quick access to ones u previously played if you forgot the name, most played also useful. But 90's music why? Is there a reason or just a random thing, or is it gonna be something boring like why ical has July 17 until u click on it in tiger which is just that's the date it came out? The only thing i can think of is to highlight smart playlists but the others do that also and have a theme?
