Identifying mp3s

[Demon Chicken]

Right, I've just been skimming through my mp3 collection and some of the files are wrongly identified.  Is there some sort of programe out there that lets me get the right titles/artist/info for all my mp3s easily?

There's this thing with mobile phones, where you ring this number and hold the phone up where it can hear the song, then you hang up and it sends you a text message about five-10 minutes later with all the details about that particular song - artist, remix, album, etc.
Dunno if it works with normal phones though, as I suspect it may be aimed at people who're pished out of their scone.
I think it's all the middle numbers on your keypad - 2580.  Might be wrong.
Don't know if that's a help, either.
