An anonymous shoutbox user posted a link to a supposed Tron Legacy track called 'Fragile'. Evidently, track 7.
Now keep in mind boys and girls THIS COULD BE A FAKE. It sounds rather generic, but it also has very similar sound to the earlier Legacy theme mp3 that's been floating around. If that was also a fake, well then, these are fakes. If not, Daft Punk is producing some pretty generic sounding, but cool, soft 80's style electro.
