Most Powerful (or Best Acted) Female Theatre Song?

https://www.youtube.com/watch?v=_B3MvJhn2Hs Donna Murphy's performance of Could I Leave You from Sondheim's Follies

Judy Kaye's "Looking for a Boy"

Sydney Lucas's "Ring of Keys"

Victoria Clark's "Fable"

Terri White's "Who's That Woman?"

Megan Hilty's "They Just Keep Moving the Line"

Angela Lansbury's "If He Walked into My Life"

Edith Piaf's "Non, je ne regrette rien" (though technically not from theatre)

And of course any rendition of "Rose's Turn."

"Strange Fruit" and the finale "Deep Song" from Lady Day by the great Audra McDonald

"On My Own" from Les Miz by Nikki M. James... I've seen so many incarnations of this from Broadway, tours, TV specials and the movie and yet much as I dislike Nikki (specially her voice) I was flabbergasted and moved to tears when I saw her sing this iconic song.... I suddenly became a fan of hers for she truly made Eponine her own.

"Days and Days" by Judy Kuhn.... So heartbreaking.... Ditto "Telephone Wire" by Beth Malone.

I wish I saw Cassie Levy singing "With You" from Ghost. That would have been on top of my list.
