Software/other to sound alert when somebody opens a certain webpage

[Hamster]

Looking to hide the audio controls and play an mp3 of YMCA loudly when a friend at work opens or tries to log into facebook. Is there any software or script that will allow me to do this? Browser used is IE. Ideally the music should keep playing even if he closes IE.
Thanks.

Thanks for the replies He doesn't use shortcuts so I'm looking for a way to play the music whenever he opens a site which has the text facebook somewhere in the URL. I'll have a look at Powershell, thanks. As for me doing the singing, It's him I want to look stupid and not me

No joy yet i'm afraid. Yes it's got to be facebook as he's rarely the person switching the pc on and everyone else will be told that 'something' will happen when he tries to log onto it. I know there's web filtering software that can block certain sites and play a sound when an attempt to access a blocked site is made but I've not found a way of changing it from a barking dog! I had a brief look at Powershell but it looks a bit complicated!
