Tagging Music played in FM Radio

[smokky]

I listen to FM radio most of the time and i want a software that could tag the song played on radio at a point of time.
dont say Shazam coz it doesnt work when i plug in my earphones for listening to the radio.

Is there any other software like Shazam that would work exactly like Track ID software in sony ericsson phones.. ???

Thanks for the help ..
