LvUrFR3NZ is a song included in the Halo 3: Original Soundtrack. It is written and performed by Greg Haupt and was released under the name of his band Princeton. The song's title uses "leet speak" and is derived from "love your friends." The song was originally titled "Ki11UrFR3NZ," but Greg was forced to change the name when Xbox said they would not publish or promote a song with a title that is spoken as "kill your friends."
