No, never heard of it. I went looking to find out what it is, Purple Rain was Prince's sixth studio album, it's like something like that. And he was also the first to be credited with the band The Revolution, I believe that's it.
There's a lot more but you did just fine. 🤗 If you ever have a chance watch the movie Purple Rain.. one of my favs from the soundtrack is When Doves Cry. 😉
