[Sudesh]

Autoplay on button doesn't work again if it gets error response once from Grooveshark server(please see attached screenshot).When we play a song for which Auto play on button works and plays song for that,afterwards when we play a song for which it gives 'Grooveshark server error response' and then again we go to play songs for which autoplay button was previously working ,the auto play button doesnt work for any song in plugin further.

Steps to reproduce:

5.Press Autoplay on,Elisa shows error message ''Grooveshark server error response'
6.Goto Popular option ,play any track
7.Press 'Auto play on'
