Wouldn't it be nice to have a stamp set commemorating the most popular women singers? Let's say rock singers to be more specific here. Some that come to my mind are Dolores O’Riordan, PJ Harvey, Janis Joplin, Joan Jett, Debbie Harry, Patti Smith. It could be a collection gathering singers of different countries. Then PJ Harvey would represent the UK, Dolores Ireland, etc. As a Pole, I would put forward Kora to represent Poland.
