It goes along the same basis of your SongID type apps like Shazam and Verizon SongID. I have had an idea for some time now but not sure how to implement it and if the technology is even available for this yet.
I really don't want to post this publicly since I don't want someone to take the idea and claim it for themselves. So if you could drop me a PM I can at least front you the idea and see what you have to say about it. I am a 3rd shifter so I'm about to go to bed but I'll get back with you around Midnight EST tonight.
