Somehow I doubt George R.R. Martin is worried about not being able to write a Landslide. On the other hand, he's eternally frustrating to fans in that instead of finishing the last two books in the Song of Ice and Fire; he devotes so much time to blogging about politics and football, pushing the latest event at his art house theater and his gallery and attending every Con and awards ceremony that comes down the pipe, so it would be par for the course if he was distracting himself by trying desperately to write a song worthy of Stevie Nick's talents.
