I use Pandora.com to listen to music in IE on Windows 8. When I switch to another app, the audio cuts out. How can I keep it playing?
I'm pretty sure that's a limitation of "metro" UI apps - assuming you're using MSIE in that mode.
If it's not the default browser, or you're using in "desktop" mode - maybe starting it from the desktop instead of the start screen - it should/may continue in the background.
