My favorites:
https://www.youtube.com/watch?v=PiLCHmyAgEU -- this dnb year mix is a bit too explosive but a lot of my favorite tracks are in there.
Chillstep, no good mixes but I've got some tracks I really like to get you started (if you're into this sort of thing).

Sometimes I do get the emotional boost from music I've never heard before, but most of the times it is from games I played a long time ago.
I'm guessing that music plays a large role in the emotions passed when playing games or watching movies.
Quite ethereal, and though I've never seen the movie, I love the soundtrack.
I do listen a lot to music from games, movies and series for that emotional boost, but it always has to be something I've already played/watched and engaged with emotionally in the past. The music doesn't generate new emotions in me, it pulls on the past experiences. Listening to arbitrary soundtracks wouldn't work on me.
