Are one of the these songs that you just sit, do nothing and listening.

Sayuri and Arrival at Barracus from Gemini Rue. Graphic + storyline + whole city are making it only better.

The Big Game from Bully

Unkle - Burn My Shadow. I don't have any idea why this song is used only in Fuel. Lyrics would have incredible big potencial in games like Max Payne, Deus Ex and not only just in games but even in anime too like Cowboy Bebop.

Songs from games like Transistor, Braid, Bastion, Kingdom Hearts, SIlent Hill, BG&E, Deus Ex etc. i won't paste here any songs because they are well-known ;p
Except The Sims 1. This is propably one of the most nostalgic song that I ever heard and it is very emotional.
