As I was reading Viola's part in Scene 5 Act 1 I was reminded of the song Dazed and Confused by Led Zeppelin. Viola is confused because she realizes that her brother is alive, and everyone thinks that she married Olivia.  

Viola’s lines

“Dazed and Confused,” by Led Zeppelin

He did me kindness, sir, drew on my side, But in conclusion put strange speech upon me. I know not what ’twas but distraction. Who does beguile you? Who does do you wrong? No, my lord, not me. My lord, I do protest— Why are you talking like this? I never hurt you. You waved your sword at me for no reason, but I was nice to you. I didn’t hurt you.  He was dressed just like you are when he drowned. If ghosts can take on someone’s body and clothes, you must be a spirit who’s come to frighten us.

Been Dazed and Confused for so long it's not true. Wanted a woman, never bargained for you. Lots of people talk and few of them know, soul of a woman was created below. You hurt and abuse tellin' all of your lies. Run around sweet baby, Lord how they hypnotize. Sweet little baby, I don't know where you've been. Gonna love you baby, here I come again. Every day I work so hard, bringin' home my hard earned pay Try to love you baby, but you push me away. Don't know where you're goin', only know just where you've been, Sweet little baby, I want you again. Been dazed and confused for so long, it's not true. Wanted a woman, never bargained for you. Take it easy baby, let them say what they will. Will your tongue wag so much when I send you the bill?

Been Dazed and Confused for so long it's not true.

Wanted a woman, never bargained for you.

No, my lord, not me.

Lots of people talk and few of them know, soul of a woman was created below.

Who does beguile you? Who does do you wrong?

You hurt and abuse tellin' all of your lies. Run around sweet baby, Lord how they hypnotize. Sweet little baby, I don't know where you've been. Gonna love you baby, here I come again.

My lord, I do protest—

Every day I work so hard, bringin' home my hard earned pay. Try to love you baby, but you push me away.

Why are you talking like this? I never hurt you. You waved your sword at me for no reason, but I was nice to you. I didn’t hurt you.

Don't know where you're goin', only know just where you've been, Sweet little baby, I want you again.

He did me kindness, sir, drew on my side, But in conclusion put strange speech upon me. I know not what ’twas but distraction.

Been dazed and confused for so long, it's not true. Wanted a woman, never bargained for you. Take it easy baby, let them say what they will.

He was dressed just like you are when he drowned. If ghosts can take on someone’s body and clothes, you must be a spirit who’s come to frighten us.

Will your tongue wag so much when I send you the bill?

I liked this combination because Led Zeppelin is talking about problems with women. In this act, Viola is having problems with Olivia, and also hiding the fact that she is a woman. Although that is not exactly what Led Zeppelin had in mind, the song and the lines fit together well. Also, I liked this combination because Viola is confused about many things throughout Act 5, just like the singer of Led Zeppelin is in his life.
