My problem with Metro IE10

I have been using Windows8 since a week before the consumer preview, and I have appreciated the updates and progress Microsoft has made. Even with a screen that does not have touch input and does not support snapping, I feel it is a fantastic operating system, and it makes me want to leave the desktop for good. However, I often want to listen to music through YouTube while I am working, and while the issue with Flash has been resolved, it stills bewilders me that playback stops when using other apps or going to the Start screen. This alone leads me to using the Desktop browser. I would love it if Microsoft fixed this. And just made Office 15 a metro app. Then I would be in Metro heaven.
