I followed my bookmark to what was supposed to be my music, and got redirected to a general "browse" page.  Even when I tried to play one of the generic playlists as a test, it kept trying to open the spotify app in order to play them.  Even when I deleted the app, it didn't help.  Now the playlists on the spotify website are all just lists, with no option to play at all.

Edit:

Turns out that it is only the open.spotify.com bookmark that redirects into useless song lists.  When I tried play.spotify.com I got the old player from several weeks ago back without being redirected to open.spotify like I had been.  If this is actually permanant then it's good, however I'm not sure what is and isn't a bug in this shifting site.
