I myself also mostly listen to instrumental music actually, It can often be a more pure expression of emotions. Well, I certainly have a few good things to recommend.
I like pretty much all the music that Monstercat publishes, though this is definitely my favorite, he is also my favorite artist from the label.
Then we have Jean Michel Jarre, who kind of popularized electronic back in the 70's. He made this really atmospheric music
You should definitely also check this album out by Toumas Holopainen, there is a small bit of lyrics, but mostly instrumental, it's like a mix of rock, world and classical. It's kind of cinematic actually, also it's inspired by a Donald Duck character ^_^
And last but not least we've got this cool chiptune music from Big Giant Circles, he specializes in chiptunes and video game music, so you'll probably like his stuff. I like his album called Impostor Nostalgia the most.
Also here is some artist you could check out for good instrumental stuff:
Parov Stelar, Zircon, Thomas-Adam Habuda, Nigel Good, Big Gigantic, Caravan Place, Approaching Nirvana, C418, Haywyre, Hans Zimmer, Ennio Morricone, everything from Monstercat, Beethoven
Edit:
You should check out the website ocremix.org
It's like a community, where people make high quality game music remixes, maybe you'll find something to your liking.
