web services - Spotify Play button issues since Web Player introduction -

our website has been having issues spotify play button since spotify web player has come existence.

there 3 issues have noticed far:

1) have click twice track play

clicking play button (when web player didn't exist) used start song playback in background. on clicking button, first launches web player (which fine) doesn't automatically start playing music. imports playlist that's does. works if user manually presses play on web player/ clicks on button second time (bad usability perspective - left our users confused). along this, confuse users further, play button shows "the track cannot played" when happens. however, if press on track again (either play button or actual web player), works fine , message goes away. tested on chrome (osx , windows 7) , safari (osx) can replicated here: http://partysen.se/event/5/tanmays-awesome-party/

2) invalid oauth token

a possibly connected problem seen since launch of web player play button saying "invalid oauth token" when trying play something. not have more information replicate it, other fact started happening on mac osx once web player launched , installed mac spotify app. tested on chrome (osx , windows 7) , safari (osx)

3) button asks app installation

another issue : on clicking play button spotify web page asks installation of app. discussed here: https://stackoverflow.com/questions/16348049/spotify-play-button-not-working-in-google-chrome

noticed in chrome in mac osx.

questions
