Skype psychology

[Froge]

Ever since MSN went down and I had to switch to Skype, I've developed a minor but intriguing mental problem. I keep hearing the skype bubble sound that indicates I've received a new message whenever I'm on the computer. My Skype could be off and I'd be listening to some music when suddenly I hear the bubble sound, and I would be distracted, for a fraction of a second, wondering if I had just received a new message. This also occurs often while playing games.

Is this common phenomena?
