Prediction of the day. Within 5 years--let's say by Christmas 2012--it will be possible to search for a song by playing or singing a bit of the song. People will be able to sing into their computer and be taken to search results where they can play and purchase the song. Or they'll be able to hold their phone up to the radio, and get a text message back with information on the song and where to buy it.

Maybe 5 years is even a bit on the long side.
