If you've ever been to an audition, you know there are many songs that MANY people will sing. Over and over, directors get annoyed with the same good but popular songs. This list gives you a decent guide to awesome sings that have some awesome variety.
I also made a playlist of precisely what versions I mean. No big deal (but you know there's a difference in versions).
1. Something sweet and romantic- Something Wonderful (The King and I)
2. Something Soulful- Mama Will Provide (Once on This Island)
3. Something dark- The Dark I Know Well (Spring Awakening)
4. Something silly- Happily Ever After (Once Upon a Mattress)
5. Something light and bubbly- The Night They Invented Champagne (Gigi)
6. Something smooth and silky- Omar Sharif (The Band's Visit)
7. Something sad- Requiem (Dear Evan Hansen)
8. Something youthful- My New Philosophy (You're A Good Man, Charlie Brown)
9. Something wistful- If You Knew My Story (Bright Star)
10. Something soul-searching (bonus if the character is LGBT)- Ring of Keys (Fun Home)
