The Warriors EP is an extended play by the rock group P.O.D..
 It was released on November 17, 1998 as a transitional album from Rescue Records to Atlantic Records.
 Only 30,000 copies were ever made which made it a collector's item and very rare to find.
 The EP contains a message from lead singer Sonny Sandoval thanking the 'Warriors', P.O.D.'s following of fans, for supporting them throughout the years before signing with Atlantic Records.
 Though produced by Atlantic Records, the album was actually released by Tooth & Nail Records.
 The entire EP is made to sound like the songs are being played through a phonograph, being mixed with a faux vinyl crackling throughout each song.
"Youth of the Nation" is a song by American Christian metal band P.O.D. It was released in December 2001 as the second single to come from their second major label album, "Satellite".

 The song was included in "Weird Al" Yankovic's polka medley "Angry White Boy Polka" from his 2003 album "Poodle Hat", despite lead singer Sonny Sandoval's mixed race background.
 It was also featured as downloadable content in the music video games "Guitar Hero 5" and "Rock Band 3".
