One of my playlists is called "64K", after the seat I had on my first BA 747 flight two years ago, AUS>LHR, my second ever trip in Business Class. I prepared the music in advance to download it, all nice relaxing tracks (Aimee Mann / Feist / Beth Gibbons / Norah Jones). I was super excited for the flight, and really happy that 64K was available, it was supposedly one of the best business class seats on the plane. Upper deck, window seat, last one on the right. No need to step over anyone, near-perfect privacy, a massive amount of storage space, and first in line to get off the plane.
I put on my playlist in shuffle after dinner, and drifted away into a very nice, long, uninterrupted sleep. When I woke up my breakfast was ready and waiting for me on the big surfaces below the windows. BA Club World has it's issues, but that flight was so memorably that I renamed my playlist from "Night Tunes" to "64K" to remember it.
