It is an ideal download for cellular phones as it pleasing to hear. 'Who knew' can be downloaded as Mono, Poly and Realphonic ringtone from most of the websites.
 
Some of the lyrics are:

You took my hand//You showed me how//You promised me you'd be around//Uh huh//That's right//I took your words//And I believed//In everything//You said to me//Yeah huh//That's right//

If someone said three years from now//You'd be long gone//I'd stand up and punch them up//Cause they're all wrong//I know better//Cause you said forever//And ever//Who knew //

These lyrics can be accessed only in Realphonic tone for the cell-phone. But, the music can be heard in all the three types of tones. A must for electronic punk band fans and couples wanting to download something nice for a change on their cellphones.
