I've been listening to the mixes for a while. It's cool that the 4th one was compiled by Com Truise.

I have been using these tracks for quite some time, the problem is that I can't manage to fully concentrate anymore without listening to them.

I find myself listening more and more to the Bonobo - Black Sands Remixed album while programming.

Before this, for a long while, I used to program listening to Joao Gilberto's awesome bossa nova. for the curious (heads up, it's just one old Brazilian guy playing on his guitar).
My newest programming music of choice is Erik Satie's trois gymnopédies. I reached them while looking into where modern Ambient artists (like Eno, see my post above) got their inspiration. It seems that Satie's gymnopédies were an important influence and precursor.
It's just about what you get used to while doing anything.

My usual choice when brainstorming is Gregorian, which would then lead me to club mixes as the picture gets clear.

Some of the most powerful music I have ever listened to is for "Infected Mushroom". I can totally develop against them. The rhythms actually help rather than distract.
Among my favorites: Ratio Schmatio, Frog Machine, Noon, Stretched. Quality loud fast powerful music.
It has been scientifically proven that baroque and ambient music help you concentrate on a intellectual task, like studying or programming.
Interesting. Could you please reference the relevant studies/papers?
Here's an old paper[pdf] that studies the relationship between listening to music and other "higher brain" functions. More precisely it studied the effects of listening to Mozart music (which isn't "ambient" nor "baroque") for 10 mins.

From the paper:
There are correlational, historical and anecdotal relationships between music cognition and other 'higher brain functions', but no causal relationship has been demonstrated between music cognition and cognitions pertaining to abstract operations such as mathematical or spatial reasoning.
My choice of music is what most (if not all) here would call noise.

Club like mixes.
You should try jazz while coding. Have a hear at this, the legendary album Kind of Blue by Miles Davis. This is what I code to and what every coder should at least experience once. If you want to go easy on your quota just listen to the track 'So What'.
@moot: amazing album. I'd also recommend Autumn Leaves by Bill Evans and Neighbourhood by Manu Katché (featuring saxophonist-extraordinaire Jan Garbarek).
