Released in late 2008, Songs From The Underground is an 8 track official compilation of favorites and rares, previously released through the band's official fan club The Linkin Park Underground. While many of the songs on this CD were only available originally through the LPU, Songs From The Underground was released to entice new people to join the LPU, and included a free LPU promo code inside for fans to create a new membership and experience what the LPU has to offer.

Currentely the album can only be found at Best Buy, although copies do appear on Amazon from time to time.
