That's all on my end. Let's see what you guys think.

Just reading this now.
Do you know that Heart - Barracuda is featured in Grand Theft Auto: San Andreas.
It's then on k dst.

K12 in Saints Row is presented as a techno station, especially in Saints Row The Third this is the case.
But i find that some tracks are missing there.
They could add some older tracks,such as

Cubik 22 - Night in Motion
R.F.T.R. - Extrasyn
Holy Noise - The Nightmare
Sequential - Psychotronic
Channel X - Groove to Move
Eq Lazer - Beat of the Feet
Overnite - The Time has Come
Second Phase - Mentasm
The Prodigy - Android
