Sia has released her single from the "Fifty Shades Of Grey" soundtrack. Is it as good as Ellie Goulding's?

In a word: no.

Now, that doesn't mean its a bad song. But its not a big hit like Ellie's is shaping up to be. In fact, Sia's song is so slow (there are a lot of 'ooohs' in it) that I bet this will be the song that plays over the end credits and not actually in the movie itself.

But I could be totally wrong. (I'm not though.)
