What is Billie Holidays best song?

I'm doing a 10-15 min presentation on Billie Holiday for my music course and I have to bring in what I feel is her best work. So I would like to know as an audience what would be her best piece, I'm looking for one that just brings out the best of her soul and voice...Thx!!!

Gloomy Sunday

Lover Man

Strange Fruit

I Love My Man (Billie's Blues)

And all the rest.

Fine and Mellow

"Strange Fruit" is indeed a song that Billie is well known for; however, I've always been partial to "Gloomy Sunday", "What a Little Moonlight Can do", "God Bless the Child", "Them There Eyes". From her later years: "You've Changed".

You can hear how her voice changes in her later years and how her life has influenced her singing style.

God Bless The Child

God bless the Child is my favorite.

Strange Fruit, God Bless the Child, Good Morning Heartache these r classic Billie songs.

Good Morning heartache

YOU GO TO MY HEAD! Any Cole Porter, Gerswhin, Hoagy Carmichael, Irving Berlin song!
