Same for the DX:HR game that weaves the song in! Before the shine wore off as you play through the whole game.
Shame what happened to the series after DX:HR (with Mankind Divided feeling rather unfinished and ending on an abrupt cliffhanger with no follow-up on the horizon, despite the game itself being great otherwise). But at least we got some really good crumbs (HR and MD) out of it, and I am very much thankful for that.
I loved the gold filter for HR, for another example. I know I am probably in the minority.
