The wonderful folks at Humble Bundle — who produce pay-what-you-like bundles of DRM-free media, inviting customers to apportion some or all of their payments to charity — have expanded from games bundles into music. The just-launched Humble Music Bundle includes work from They Might Be Giants, OK Go, MC Frontalot, Christopher Tin, Jonathan Coulton, and Hitoshi Sakimoto. It's DRM-free, it's pay-what-you-like, and it's amazing music, too.
