I was just about to reply to some duder with a YT video link response to his silly statement: "I only play P99 because it's free." But you should always check media before sharing it on the interwebz, so I did.
I found an an EQ easter egg. Name that zone.
The song was released March 30, 1999 (2 weeks after EQ) and the music video would have come a bit later.
The Offspring = EQ fans? Maybe their sound guy.
Or were sound libraries so limited in 1999 they happened to use the same one? Or just...巧合？
