EAST RUTHERFORD, New Jersey — Ke$ha's recent performance on "Saturday Night Live" was divisive, to put it mildly.

Some saw her two-song set — which featured laser beams, body paint, spoken-word interludes, dancing astronauts, fireworks and an American-flag cape — as an attempt at "artistic expression" gone awry, while others praised her efforts, calling the performance "spirited" and writing pieces in her "defen$e."

Either way, it didn't really matter to Ke$ha. As she told MTV News on Saturday at the Bamboozle festival, she's not listening to anything anyone has to say about her these days.

"If you don't like dancing astronauts, laser beams that play music, me talking about aliens, glow-in the dark things, vocoders and a hot chick, I don't know what to tell you," she laughed. "My new theory is ... I don't really listen or look at anything. But I have heard through the grapevine that some people thought it sucked and some people thought it was great. [I] don't care. I had a fun time. I played laser beams."

She did, indeed. If anything, Ke$ha didn't think the backlash from her "SNL" appearance had anything to do with, you know, her actual performances as it did with the fact that she refuses to be categorized. In an increasingly segmented industry, she proudly — almost defiantly — sticks out like a sore thumb. A sore thumb with laser beams, of course.

"I don't use Auto-Tune. I come from a country-music-writing family, a punk-rock loving brother who gave me his records, and in a society where everything is supposed to be perfect — down to what I wear, what I look like, my body, my voice, my outfits — I'm not perfect, and I embrace it," she said. "And I think that's what a lot of people are finding not being up to par to, like, the standard that other people have set, but I'm just being real. And I think what I'm doing is good."
