Buddhists often chant mantras to stay in meditation. I suspect that a steady beat / rhythm has a lot more to do with concentrating than any specific genre. It gets the rest of our minds jogging along with the thing we're trying to achieve.

Wow, you're really asking for a lawsuit aren't you? I mean, MP3s available for download for free on a simple HTML website? What is this, 1998?

Instrumental classical mix works best for me. I put on Mozart or Beethoven radio on last.fm and just skip all the stuff with words (i.e. opera)

My favorite album to listen to while I code is probably Blockhead's "The Music Scene." Gets the blood pumping.

1. As vishaldpatel notes, the pattern resembles meditative mantras. However the mind reacts to religious chanting, "trance" resembles that and invokes similar focus to the exclusion of other distractions. Indeed, we call the music "trance" for a reason.

2. The music does not demand attention to itself. Most other music is created with a "drop what your doing and pay attention to ME" sense, and we go to concerts and pay good money to listen to such music for what it is as the center of our attention at that time. Dance music derived from ambient origins creates a beautiful backdrop to something else, driving away other distractions and setting a pleasant environment for whatever we really want to do; most of it is created for, well, dancing - but the style where the focus is on self & moment, not on music or others & events.

In our culture, very little else combines to create this audio backdrop combining meditation and high energy. Most instruments demand the musician(s) focus on a full performance, and hence expect (hope?) the audience to give similar attention - the antithesis of what we're looking for here. Even "minimalist" acoustic[ish] music like Philip Glass & Steve Reich, which resembles "trance", requires an intense single-performance effort & focus of the performers, giving the implication to the audience that similar focus should return the favor.

Electronic music allows lots of free-running loops, zero-effort samples, edited-to-perfection sequences, and time-unconstrained editing after the fact - to wit, it's not created live, not intended for live performance, and the artist has no attitude of "I'm not utterly focused on perfect end-to-end performance of this, so I don't expect utter focus of the audience". Acoustic meditative music heads this way, but involves the performer in the focused activity; music isn't an ingrained part/consequence of coding.

Upshot: electronic music lends itself to creating coding-productive music. We'd like such music from other sources, but nothing else lends itself to producing such high-energy long-run content without demanding the listener's attention.
