Hard choice. I'll name some of my favorites instead: What We Don't Know Primo Slip So Far Away Halo Debris Robot Boy (Demo) Change (By Beta State) if that song even counts
Tossup between No Laundry, One Step Closer live with Jonathan Davis, and Pale. No Laundry: Easily the most relatable Linkin Park song for me. I hate doing laundry and to hear Chester's frustration at the chore really helps me get through it when I know it needs to be done. One Step Closer (featuring Jonathan Davis): Add my favorite vocalist to one of my favorite songs by one of my favorite bands. It's just a recipe for awesomeness. Pale: My favorite Linkin Park instrumental until Drawbar came out. I love the way this track builds into the epic finale. Sounds really good with Waiting For The End vocals.
Pale, What We Don't Know, Pretend to Be, Primo, Across the Line, and the whole LPU 8. I'm serious about LPU 8
I love Primo, I love it much more than I'll be Gone, the vocals aren't as forced, and the meaning and lyrics are beautiful
Figure.09 demo, way superior to album version (those screams at the bride) White Noise, sounds awesome and creepy at the same. Makes you terryfied. Coal, awesome while you read creepy pastas Part Of Me demo, again, superior to the final version (awesome screams on every chorus). Pictureboard
My favorites are probably Dedicated, Primo, Debris, Drum Song, Drawing and, above all, 26 Lettaz in Da Alphabet.
