This week’s productivity-killer has the potential to keep you preoccupied for quite sometime—which depending on your motivation level at work today—could be a good thing.

This website has a collection of audio clips, all played in B flat. You can start playing the clips in any order, and they’ll create a cool soundtrack. You can play all of them, or just a few. Tinker with the volume, adjust the timing, it makes no difference—the combo will always blend. It’s kind of random, but fun to toy with nonetheless.
