Radiohead - In Rainbows - DiscBox

I bought the Disc Box version of the new Radiohead album In Rainbows today. Pretty sweet. I get the downloads tomorrow like all of the downloadering people but I also get a CD (with extra songs) and an LP version. I'm not sure if the LP version has the extra songs or not. Sure it's 40 pounds... or over $80 in US dollars. But... I love what they are doing with this thing so I wanted to do it full out. Plus it's fuckin' Radiohead.
