It launched in Britain. I remember dialing 2580 in a nightclub, waving the phone around, and everyone being impressed when the identification was correct, as it usually was. Even with relatively obscure music.

A friend was in the beta and demoed it to us in a bar.. it was insane

In the UK you dialled 2580 from your (non smart) cellphone, it would hang up after a few seconds and you’d get an SMS right away with the ID of the track
