I want to whistle a tune into my computer and have Google search the web for the same musical signatures and find all the songs with that tune. Perhaps just be able to hum literally a few bars and get the web to discover the gist of the tune, then find it for me.
Case in point, the Periodic Song that my friend Damien Potts introduced me to. He passed away recently, and I didn't have the sense to ask him who sang it. Might as well also have Google embed a simple tuner and metronome into the search page to make sure you got the notes right. Heck, integrate it into Garage Band for me while you're at it, so I can plunk a few notes on my midi device to have the tune discovered out there.
Now playing: Damien Potts - Periodic Song
