R&B singer Brandy disguised herself and began singing on a crowded train. The reaction she got might not surprise you.

Brandy (AKA Brandy Norwood, AKA Bran' Nu) has been in New York recently, making her Broadway debut as Roxie Hart in Chicago. There are still some things she hasn't gotten accustomed to, however – like the fact that everyone in New York lives in their own tiny bubble and is terrified of interacting with strangers.

So when she rode the subway with her friend Frank, who brought a camera, she didn't see anything unusual with belting out a few soulful bars. How did the strangers on the train react? They didn't.
