Any performer looking to get an ego check can do it for just $2.75: Like Brandy did last week, they can board a New York City subway train and start showing off their art.

As you may recall, a video of Brandy singing her "heart out" on the No. 1 train in Manhattan went viral last week when she posted it for her fans. It's since racked up over 2.1 million views. Brandy was amazing, but we suspect that wasn't all that was behind those hits.

Instead, it was equally amazing to see the almost complete indifference of the subway riders around her.

We had some theories as to why it went down this way. But Brandy herself had the best reaction, as she shared on TODAY Tuesday.

"I thought it was hilarious!" she said, explaining she'd made the video for her blog readers. "I thought my fans would get a kick out of me going on the subway, being spontaneous and nobody reacting to my singing."

Even better, she reported that she did get a reaction from one rider — advice on how to make a career out of her pipes. "He told me to 'go a little bit harder,'" she recalled. "'Go bigger. ... You have potential, you might make it, but you were not as over the top as you need to be.'"

She's planning to do it again — that is if she can find time between starring in "Chicago" on Broadway and appearing on her new BET show "Zoe Moon."

"I definitely want to go back on another train," she said. "It was so much fun, and people really thought I was, like, upset. I'm like, 'People, I wasn't upset.' ... I'm a spontaneous, adventurous person."

And she won't need any help: When Al Roker tried to give her a MetroCard, she turned him down. "I've got my own!" she said.
