Web Player hangs when hit play button of empty playlist (with unavailable songs on it)

[vegaquark]

I'm experiencing a hang on the whole web application when i hit the play button of a playlist full of unavailable songs. 

It's with my pantha du prince playlist, wich have unavailable songs on it (greyed out)... 

Maybe the function that starts playing songs of a playlist hangs when no available songs are present on the playlist, or keeps rotating from song to song on a infinite loop.

Please check that spotify programmers.

See you!
