Today (a day in November 2015 at the time of writing) I stumbled upon the album Electronica 1: The Time Machine from Jean-Michel Jarre.
It's mainly without vocals (which I prefer for coding).
An interesting finding from a coders perspective: The title If..! is among the exceptions.
A few weeks ago (early 2017 at the time of writing) Vasko, a colleague of mine, pointed me to Best of Shingo Nakamura (2-Hour Melodic Progressive House Mix)
If you like C64 music than Slay Radio might be worth a try. tune in
