Adding Music - Yes or No?

NO! NO! NO!
In this day and age, there are so many different genre's of music that it is hard for a single individual to choose a song that appeals to everyone. Most people when browsing the internet, for either work or play, are usually listening to their own music.
Think about how embarassing it would be sitting in your cubicle and when you go to a website, BOOM - AC/DC is screaming out of your speakers, and before you have a chance to hit the "X" or turn your speakers off, you are embarassed, in trouble and agitated. What are the chances of you returning to that site again?
So no, adding music is not usually a way to keep viewers coming back unless you are a musician or in that type of industry.
