Can someone tell me the phone number you ring and hold the phone to the music to find artist?

I'm in the UK, and it's classical music, will it find it?

Its 2 5 8 0
straight down the middle of your phone's keypad.

I think it's 2810, though I could be wrong. It's a 4-digit number, and I'll tell you next time the ad is on.

2580,just the numbers down the middle of your phone keypad.
i don't know if you'll be able to find classical music..i guess it's worth a shot though.
type the phone number into google or something first and look on the site to see how much the calls cost before ringing up and wasting a tenner :p

The service is called Shazam and it is 2580. I've attached their url x
