Chris,
you won't find any artist's website where you will be allowed to post copyright protected material whatsoever.
David Gray is extremely liberal regarding live recordings though. He allows fans to share those as long as there is no money involved, the majority of other artists don't. So please respect David Gray's copyrights regarding officially released material. And other bands' copyrights that got affected in your post that was deleted.
As for the tracks on the front page; this is David's own website after all and it is his decision if he wants to share one or some of his songs.
