Pandora or Spotify...which do you prefer?

Here at fix8, we listen to a lot of streaming music.  For years, Pandora was our answer.  And, after years, we've all built some pretty custom stations that suit our mood at any given moment.  But then came Spotify...And, even after some resistance as a loyal Pandora user, I've found myself using Spotify more and more.  Recently, I thought about perhaps actually subscribing to their premium service...but, if I was going to consider  paying for a service like this...I thought I'd do a bit of research.  I came across this great infographic and thought we'd share.  What's your flavor of choice...Pandora...or Spotify?
