What a glorious time it was with that master playlist and the excellent keyboard shortcuts. I used to put it on shuffle and play a game where I'd press Next and then Pause immediately and try to impress friends by knowing what song it was within the first half-second.

You could also just conjure up any song with the "J" keyboard shortcut that would search the entire path as well as the ID3 tags. It was so good that one weekend night in high-school, my friend and I decided to put an old desktop in the back of my Jeep on foam and power it with an inverter. We ran aux wires to the stereo and I literally just had a full-on keyboard that I could pull up while driving and get any song in my library with a few slaps of one hand without looking down even once (I knew one-handed typing skills would be useful someday). (I even tried voice command with Dragon Naturally Speaking but it only worked when the engine was off.) To this day, I haven't had such an agile interface to my music. I just use a phone now but it has a fraction of my old library and searching for things while driving is dangerous, illegal, slow, and miserable.
