Freddie Mercury Good Music Doesn’t Have An Expiration Date Shirt! This morning, on Women’s Wear Daily website I found an article about Killer Queen. Here are some important pieces. Katy Perry would like to make one thing absolutely clear. She doesn’t allow her life to be ruled by fear. This is how I view my career not as a ticking bomb, said Perry. A lot of people do things out of fear. A lot of people make choices they won’t have a career in five years. I know where I am, I know what I do is worth something and does not have an expiration date on it.
