@Pandora make it hard, I however can make this choice easy because I choose Posse 1,2,3,4,5,6. Every one has music artists that I really like, and everyone has a music artist and or artists that has music that I don't like. That is my choice and I'm sticking with it.
Take care and stay safe.
I'm going to break the mold and go with posse #7 (not listed)
Suzuka Nakamoto (Babymetal)
There are so, so, so many more great female singers, but these are ones that have sung lyrics that meant a lot to me.
