These are some samples of the two of best known composers of our time. My favourite of the two is definitely John Williams for his melodic touch he always brings to all the genres he composes for whether it's horror, action, drama, adventure or sci-fi.

I like a lot of other composers too so no need to comment "there are other composers too you braindead fool". John Barry, Ennio Morricone, Bernard Hermann, Eric Serra, James Horner, Brian Tyler, Lalo Schifrin, Danny Elfman are only some of the composers I like.
