Game and movie soundtracks are great for work. Particularly when they are just scores or choirs (as opposed to bands, duets, or single vocalists). Way less distracting.
I've made a spotify playlist that tries to mirror it. It's not as good as the real thing but it's a start:

From Wikipedia: Ozric music is a highly psychedelic mixture of driving basslines, keyboard and intricate guitar work, with a sound influenced by Steve Hillage and Gong. Many of the Ozrics' songs are in unusual time signatures and/or unusual Eastern-influenced modes. Furthermore, the band often features complex arrangements, which change time signature, key signature and tempo frequently in the course of a track, a well-known element present in progressive rock. There are also moments of straightforward funk-influenced grooves and strong influences from jazz fusion, dub/reggae and ambient music styles.
These features are mixed with electronic elements, including densely layered psytrance- and techno-influenced arpeggiated synthesizers, pads, synth basslines, effects and programmed drumbeats. There is also a strong influence from dub and ambient music, with many quiet relaxed tracks, that balance the frenetic, intense material.
If that is up your alley, I can recommend the following artists:
Boards of Canada come to mind. Carbon Based Lifeforms (especially their album "Twenty Three"). Marconi Union. Steve Roach made some pretty awesome stuff (Structures From Silence especially).
Every now and then - rarely, actually, but that is not a statement - I will get out the Cocteau Twins. There are lots of vocals, of course, but rarely anything resembling lyrics, so that works for me.
Also, some of the stuff Dead Can Dance made before they split up was pretty great. Towards the Within and Spiritchaser were quite great.
I've thought about this myself and tried to find music to listen to while programming or writing. Haven't found too much that I like, somehow. Will check out the links in this thread.
Here is one that I do like - blogged about it here, with a link and embed to the music, and someone I know also said they liked it for working - a sitar performance by Vilayat Khan (Rarely Heard Ragas), who was of the calibre of Ravi Shankar:

The Crypt of the Necrodancer soundtrack is really great: https://www.youtube.com/watch?v=UrS1RyuoG0I
Instrumental prog is pretty good: Liquid Tension Experiment, Joe Satriani, Scale the Summit...

I also really liked this set, but some people may find it a bit much: https://chibitech.bandcamp.com/album/chibi-tech-live-blip-fe...

Thanks for the hint, I will see how that goes. :)
Not that I am judging in any way. I used to listen to a lot of Heavy Metal, and I still do occasionally (especially when I am angry/frustrated - it seems to have a cathartic effect on me).
For programming, I prefer calm, quiet, unobtrusive music, but apparently there are many programmers out there who like to rock. :)
8tracks has a lot of great playlists. The key is finding a user who makes good ones. This yellowcake guy has over a hundred, of which almost all are great.
I've been listening to a playlist I found on Spotify - "Beats to think to"
Also, if you like the sounds of a coffee shop, checkout coffitivity.com (no affiliation). If I'm in the right mood, gets me in the zone.
I think it is the acoustic equivalent to the Clippy effect: Human voices tend to take up a substantial portion of our mental bandwidth, because it is not just a sound our brain has to recognize, but then it has to go and actually understand the words being said or sung.
Instrumental music tends to have - at least on me - the opposite effect, it occupies the parts of my mind that otherwise might distract me, leaving the parts doing the hard work alone.
I find Trance has enough energy/momentum to motivate me, without being distracting like most of the rock/metal/otherstuff I listen to other times.
A couple links that have crossed the HN Radar before:
