1. The Order of Death - Public Image Ltd. Quite possibly one of the most fitting hooks, IMO. Repeats over and over "this is what you want, this is what you get." Perfectly sums up Elliot's troubles with Evil Corp and the subsequent fallout, the far-reaching effects of which will still be seen throughout the next season, I'm sure. And the genre fits in nicely, I think.
2. Stuck On You - Failure. Maybe this one is a little on the nose but it's about drug addiction. Although Elliot's morphine/Adderall usage has kinda taken a back seat in more recent episodes, I also think the lyrics really reflect his codependency with Mr. Robot.

I don't have any thoughts on what would be happening scene-wise during either of these songs, but I think they could work well somewhere. I thought the same about "Walking In My Shoes" by Depeche Mode when I first started the series and sure enough, they ended up using it in Season 2.
