Kinda OT but it’s funny, iTunes and iPod playlists can be as long as you want them to be but I like trying to make mine under 80 minutes. It’s like trying to make pieces of a puzzle fit. I just edited my St. Patrick’s Day playlist and it’s thirteen seconds under 80 minutes because I replaced one song with another. Really think I have this flowing well since I have traditional and new songs alike and various types of music.
