Lifehacker links to musicForProgramming(), a site that packages one-hour ambient mixes for white-collar work. Unfortunately, as I write this the site is down, either due to being slashdotted by Lifehacker, or because they didn’t mind their jots and tittles regarding copyright before they got major notice.

Web site musicForProgramming(); distributes a series of roughly hour-long ambient music mixes intended to “aid concentration and increase productivity” while you work.

I’ve long been a fan of Above and Beyond: Trance Around the World‘s iTunes podcast for the same reason. Two-hour blocks of techno/trance without much voiceover, it’s good for either a writing or cogitation session. And with 400+ episodes in the available archive, you’re not going to run out of music anytime soon.
