This is probably something to do with Apple's announcement of tiered pricing and DRM-free tracks yesterday. While the big labels had inside info and got their stuff ready, I suspect Apple stopped leaks by not telling indies like underworldlive.com their plans in advance. Apple have announced 256 kbps DRM free versions of *all* tracks will be available through iTunes by March.
