I wouldn't call myself a big NIN fan but I saw today that they've released a full album for free on their website. I know they released Ghosts for free a while ago but this is a full album. Could mark a real change in how bands approach music.
There are plans for a cd version to come out soon but most people will already have heard it by then. It'll be very interesting to see how many people go out and buy it.
One major plus point in it's favour is that because it's so easy to get it may introduce them to a whole new range of fans. I would never have bought it in the shops but since it's free I downloaded it in about 5mins and am listening to it as I write. And it's good. Fair play to them. Download it here
