so you're getting the raw file along with it's huge size.

if you're savvy with transcoding, which I'm assuming you're not, you can convert the file to lossless formats like .FLAC (not iPod compatible) or lossy formats like .mp3, ALAC, etc.

I don't quite agree with Radiohead charging different prices for lossless and lossy formats, but whatever.

like howisya suggested, you're probably better off going with the 320kbps version, as I doubt anyone can really tell the difference (inb4 controversy).
