You're in Def Leppard. Your band has written some of the most popular rock songs of all time–tunes like "Photograph," "Rock of Ages," "Foolin'" and "Bringin' on the Heartbreak," to name just a few.
Your album sales–including "Hysteria" and "Pyromania"–are among the best-selling rock albums of all time, with more than 65 million copies sold.
And then the market changes. Grunge and then hip-hop start to dominate the charts, and the rise of file-sharing means that it's all the more difficult for any artist, in any genre, to sell in the numbers of previous eras.
What do you do? If you're in Def Leppard, you respect the music and keep on rockin'.
