I feel the need to step in and clear up a couple of things before further misunderstandings take hold:
As Clemens stated above, I composed everything on the HM3 Soundtrack.
Not a note was written or produced by anyone else.
As for HM2, everything on the Original Soundtrack release was composed by me.
Some tracks you’ll not find on that release are tracks played as source music in various locations, like the Miami Driver’s Lounge and surrounding areas.
The music here is a collection of licensed tracks, as credited in the game, and tracks created for the game by Dynamedion.
I did not write these tracks, including the Driver’s Lounge EDM.
Phew, there it is. I hope that’ll put an end to all the “who wrote what” speculations 
I’m new to this forum and above all: Thanks for all the kind words about the music! Truly appreciated.
