Anti-metallica pro Mars Volta enter sandman ringtone...?

I heard it a long time ago on windows media player under the guide, maybe a year or 2. it was enter sandman, but it was like a ringtone, and the lyrics were done by two wierd inhuman male and female voices. it sounded real cool, except for the end when the voices said "metallica sucks, mars volta is a hit rock sellout" or something like that. whatever it was, i didn't like the comment at the end, but the song was really cool. does anyone know where i can hear it now? its not on windows media player anymore.
