They are definitely a bit darker, more tech-house. I guess the style changes within each show, but from show to show it's consistent. The first half of each show is generally low-key tech-house, but then I start speeding it up a small amount and using more "busy" progressive house tracks later in the episode. But not many vocals in each. Some people will like these better (the sound quality is also better), but some coders will definitely prefer the six older "Music To Code" By mixes.
