The Splitting the DNA album is a bootleg album(fake album). CD 1 contains 20 songs, demos and live performances, all by Linkin Park. CD 2 contains 20 songs by Grey Daze. Grey Daze is Chester Benningtons(lead vocal and frontman of Linkin Park) former band. Tagging Linkin Park as the band for all the songs from CD 2 is therefore wrong, the right tag is Grey Daze.
