FINALLY, I know the names of ALL the songs:
1° song (0:00 - 1:01): Celldweller - Own Little World (Eternity Remix).
2° song (1:02 - 4:58):
Heavenly - Illusion Part II (The Call of the Wild). Btw, the phrase at
the beginning "Are you ready?" is taken from Crissangel - Mindfreak.
3° song (5:05 - 7:22): Wildpath - Everlasting Wish.
4° song (7:23 - 7:56): Celldweller - Birthright (Beta version 1.0).
So, now you can stop asking and thanking me putting "like" on this comment. :)
