I want to go back to Windows 7

I am loving the fluidity and UI of Windows 8, disappointed in the functionality department. I was on skype this morning, I had to put the volume down on skype as I wanted to play a song on Media player to make the one whom I was calling to listen the song. I realized I couldn't do it, If i turned down the volume, it has to be for the whole system, this wasn't the case in Windows 7, or the non "metro" version of Skype. Music app sucks, Video app sucks, I want to love it, Microsoft is giving me a hard time :(
