For songs with out words or with very few I recommend:

    Sigur Ros, which is just pure amazing
    John Murphy, adagio in D minor will most definetily amaze you
    Hans Zimmer, inception, Rush, da Vinci code, batman dark knight, man of steel
    Ludovico Einaudi, all songs especially Divenire and Nuvole Bianche
    Tim Shiel, although he done music for the game Duet, his work isn't that bad
    Thomas Newman, almost martyrs is great
    Steve Jablonsky, a lot like hans Zimmer as they both make music for films
    Randy Edelman, his best is probably to the stars
    Moyà Brennan
    Jonathan Goldstein, magical moments is pretty good
    Helios, YOU NEED TO GET THE WHOLE EINGYA ALBUM
    Alexandre Desplat, the music from the Imitation Game
    Alex Heffes, sons of Xhosa from nelson Mandela long walk of freedom will make you cry, or type with much greater speed
    Trent Reznor and Atticus Ross, from the social networking
    John Williams, why not?
    James Horner, from BraveHeart
    Michael Kamen, band of brothers
    Hans Zimmer and Geoff Zanelli and Blake Neely, opposate of band of brothers - The Pacific
    Johann Johannsson, the theory of everything composer
