To me, the Sam Smith "Won't Back Down" case was much more straight-forward: http://www.youtube.com/watch?v=qkcZV97O3pw

But that's a very simple chord progression with common vocal hits, whereas this case seems to hinge on a very distinctive bass line and percussive style.

Much more straight-forward. Much closer to being the same thing.

Would still have been pretty ridiculous if a verdict had been made that this counted as copyright infringement. (They settled it amicably)
