3. Madonna
She might not be as trendy now as she was back in the day, but there’s no denying that Madonna is one of the pop pioneers of our world. She was considered extremely edgy when compared to more wholesome pop icons like Michael Jackson, and was one of the first women in the 1980s and its male-dominated pop music industry. While she’s not everyone’s cup of tea, she’s still considered an A-list celebrities and has put out music in recent years.
