Windows 8 Concerns

I want to dual boot windows 8 on my macbook but after using it in parallels i have some fears and was hoping that someone could answer my questions about some of the points of the OS.

First is that i often have music playing in the background in a browser but in the IE10 in metro it doesn't keep playing when i switch apps. Is this normal or is this something that can be remedied?

Secondly is that I have a lot of media and i haven't, as yet, moved any media in to the apps. Is the music app any good at handling large libraries? and can you sort tv shows from movies in the Video app?

Thirdly how are you finding as your daily driver? is it up to the task?

Cheers for any help in advance!
