I personally prefer most of the demos because the lyrics were beter and I wanted something knew after I got sick f the origanal songs.
Thats a tough quiestion actualy,i mean i prefer esual to place for my head,dedicated should have been released,i prefer the crawling demo and the points of authority demo but i'd still say the studio releases
I like the demos. IMO quite often it's possible to way overlisten to songs and I definitely did that with Hybrid Theory. So it's cool that the demos are there so you can listen to the music but it's a little bit different.
