I always knew iTunes could do playlists, but I never thought about why. I only thought of them as a way to put the songs you like more than others in a special place to help find them. Somehow it finally dawned on me that I can organize my songs on how they sound to make different play lists I can listen to depending on my mood. This was a nifty discovery, but then I also noticed that I can not only make play lists with certain songs, but put them in an order in that play list so it tells a story. Ain't that nifty?
