My new phone has the Sony Ericsson TrackID thing and it's bloody amazing. It records a small sample of a song, sends it off to the interwebs, and it comes back and tells me the song and artist and album. I've been playing with it for awhile, and it's always right, it's like it's reading my mind. The only time it failed me while testing was on the beginning of Hysteria by Muse....it came back and told me it was Interlude by Muse. Same band, same album, so even then, that's impressive. Anyone know the technology behind this, like how it actually works? Because it's nothing short of amazing and I'm really curious.
