Yesterday some developers who have access to Apple’s beta applications started showing some videos of how well Apple’s upcoming iTunes Match service will work. It is one of those ideas that are brilliantly simple, yet one does not know how Apple pulled it off.
iTunes Match works like this – you have your music library (which you might have gotten very various sources, they do not all have to be purchased through iTunes), and then Apple goes and scans your library. Once Apple has these tracks it matches it to their massive iTunes catalogue, and then makes that catalogue available to your from any of your other authorized machines with iTunes, and all your authorized iOS devices like iPod, iPhone and iPad.
The other great part is that once the library is scanned it does not go along and upload all those gigs of music – the matching service makes iTunes 256kpbs AAC files available to download on the other devices. Have some bad 96kpbs track you ripped a long time ago? You can now get the “matched” file with iTunes match in good quality.
