Shuffle Songs Repeated by Artist in last few updates.

I've been pretty happy with the shuffle algorithm Spotify uses.  In the most recent few updates though, at least on my iPhone, I get a lot of repeats by the same artist two songs in a row. (My playlist has 658 songs in it.  29 of which are Streetlight Manifesto, for this example).  Browsing through the play queue that was generated by a shuffle, I found 3 or 4 band duplicates in a row.

This blog post suggests that this shouldn't happen:

Has something changed in the shuffle algorithm?

Another example.  Browsed to my playlist just now.  Click the green "Shuffle Play" Button. Clicked the play queue button.  You can see Alkaine Trio coming up twice in a row.
