Still Alive is Up and Early!!!

This was announced earlier today for to be released tomorrow, but apparently someone pulled the trigger to put it early on both XBL Marketplace and the Rock Band store.  Still Alive, the end song from Portal, is up and it is what u expect from a free song which is easy and simple on guitar (Expert). Maybe drums are a different story from what I read, but Portal fans should download this in a heartbeat. Kind of cool that this is the first free song for Rock Band considering a handful of free songs in Guitar Hero III. Here's already a video of someone FCing it (the first video I found).
