Benjamin Briggs makes a lot of good stuff. I'm a bit of a NES nostalgic when coding. My love for coding began in 98 when I built my first website (a Zelda 64 Ocarina of Time fan-site)
I'm not too much into impressionists, but I love Debussy.
For Baroque; Start with the king, Bach. Beware though, some complained it takes away from their brain cycles.
Concerto in A Minor for Four Harpsichords:

Just give yourself a bit of time to get familiar with tonality and harmony.
When I'm bored and going through the motions working on something that doesn't need great thought I listen to podcasts or put Netflix on in the background for background noise.
For hacking it's essential that lyrics don't take up any brainspace, as (at least for me) the verbal part of brain needs to 'hear code' I'm reading/writing.
So it's either something purely instrumental (say, Apocalyptica), something completely foreign (j-rock? most european languages don't work as too many words are semi-understandable), or something that I've listened to for a dozen years and know entirely by heart.
Sometimes guitar based music: Robben Ford, Matt Schofield, Johnny A, Satriani etc
Sometimes electronic/pop: Daft Punk, Empire of the Sun, Cut Copy, Ratatat, El Ten Eleven
Sometimes electro swing: Parov Stelar, similar on pandora radio
Lots of Rdio radio and Pandora lately, influenced by one of above. Lately Rdio seems to introduce more artists than Pandora, and has more features (adventurous, artist only)....
Ford is great. I'm a guitar player myself, and I feel hearing scales and fast guitar playing keeps me going when working. Lyrics on the other hand can be distracting, unless foreign. There's a Norwegian band, Kaiser's Orchestra, that I listen to occasionally. http://youtu.be/8ZkFXnm-RNQ
I am one of those who can't have lyrics in the background. I like a mix of light classical and modern (Satie to Glass) along with cool jazz (if you include Sketches of Spain in that category). For my late nights I tend to go with Boards of Canada though.
Mainly Instrumental for me.
It varies from movie soundtracks (especially by Hans Zimmer) to classical and even trance or digital mmusic (which you can find in http://di.fm).
Anything with a good consistent rhythm and beat is good for me. I particularly find that (surprisingly!) liquid Drum & Bass helps get you in 'the zone' of concentration.
it varies, but usually works best with music I'm already familiar with
today is was
1) the Fretless (irish classical hybrid)
2) Foo Fighters
3) Eve 6
sometimes I'll stream wmbr (wmbr.org). They have a variety of music thats usually good. They archive the shows to for later listen if you don't like whats on now.
Yeah, they code up their own 'instruments' in Max/MSP and some of their music is algorithmically generated.
Of particular note is 'Flutter', a track where no two bars are the same, which was produced in response to the UK Government passing an 'anti-rave' law which attempted to classify dance/electronic music as 'repetitive beat music'. Party organisers were encouraged to have a copy of Flutter, a musicologist and a solicitor on hand in the event of the police trying to enforce these crazy laws. Fun times!
I use it like a Pomodoro timer. I start the recording, I work for 51 minutes and when it is over I take a break.
The recording has a nice mix of relaxed and energetic segments and it is sufficiently repetitive that it isn't distracting.
