A somewhat unheralded benefit of the new iTunes Match service is that it allows you to (under certain circumstances...) dispense with having to have iTunes running on a computer, or even have a computer on at all. The latest updates to the AppleTV software gave you the opportunity to turn on iTunes Match. Now that the service is up and running (and I've uploaded and matched my library) I gave it a try. The first time you select iTunes Match (which has its own separate menu) it takes a little while to load the data on your library - about two minutes for my 5000 song collection. Once the data is loaded, you get access to all your playlists, songs, album art. Once you pick a song or playlist it streams impressively quickly - only slightly slower than when streaming from my computer over wifi. Obviously this isn't going to be the first choice if you quickly switch between a big variety of songs. There were a couple of glitches. For some reason a couple of songs in one playlist got an error message: "Content Not Found" - I'll need to investigate the iTunes Match status of those tunes. Still more experimenting to be done (for instance will it let me stream my US library if I'm in Europe.) But all in all, a massive development. And the promise of freedom from having to have a computer on someplace in my house before listening to music over the AppleTV.
