I love using Grooveshark.com to play music on my phone through the browser. At first when I got the phone I was able to have a song playing from Grooveshark in the Internet app and could navigate away from the window (go to the home screen, etc) without the music stopping. Recently I was trying to speed up my phone and was going through and stopping processes I didn't think were necessary. After doing that I noticed that when I'm listening to music on Grooveshark and I move away from the page, the music stops.

Did I accidentally remove some kind of plugin that allows media to continue streaming after moving to a new window or application? I'd like to be able to listen to my music on Grooveshark and navigate to other apps on my phone at the same time.

Any help or ideas would be appreciated, thanks!
