Guitar Hero Addiction or just good fun???

Is it a sign of a problem when you are listening to the radio and a song comes on and your kids shout, even the two year olds, "Hey this is on Guitar Hero"??? Well we don't even have a game system or TV but when I am at my parents we LOVE (or just I LOVE) to play Guitar Hero. Makayla knows all the words to Slow Ride. It came on the radio the other day (yes I listen to Classic Rock) when it was over she asked to have that come on again. I am beginning to notice songs on the radio not for the songs own merit but because I have played it on Guitar Hero. When I was watching my aunt and uncles kids we were up till wee hours of the morning play Rock Band. I was supposed to be the roll model and example. I guess like one of my brothers friends said when he watched me play guitar hero "You are a cool Mom." Of course my sister in law can school just about anyone in Guitar Hero- she rocks. Staci could be a total Rock Legend! But I do love the game and spend too much time playing it and ignoring kids when I am at my parents. Is this an addiction that I should be seeing someone for???
