Coldplay's "A Rush of Blood to the Head" is in general a very good album!

Pretty much anything by Disturbed.

Anything from Two Steps From Hell.
Also Graeme Revell makes really good movie soundtracks, his music in Red Planet is amazing.

Armin van Buuren - Drowning (Avicii Remix) (The extenden mix, the radio mix on YT is not comparebale)
