Piers Morgan declared Tuesday's semi-final round of competition on America's Got Talent
the best on the show to date.
Morgan and the other judges, Sharon Osbourn and Howie Mandel, heaped their praise on musical group Poplyfe, who performed "Come Together" by the Beatles, putting their own soulful, rock 'n' roll twist on the well known song.
"You blew me away," Mandel said. "You guys are already stars."
Osbourne said she felt she was "looking at a winner," and Morgan agreed, telling Poplyfe they're sure to be a "huge band in this country."
Also winning over the judges was the light-suit clad dance group, Team iLuminate, who received an uproarious standing ovation from the audience as well.
"You should have been famous forever ago already," Osbourne said of the troupe, who performed a flashy and lively video game-themed dance battle.
Miami All Stars' performance received the judges' stamp of approval as well, with Morgan declaring the high-energy swing-dance routine his "favorite performance of the whole night."
However, not all the acts fared as well with the judges. Morgan buzzed Sandou Trio Russian Bar shortly into their performance, which featured singing and a suspended, twisting piano rather than their usual acrobatics.
"You made a bad choice," Howie said of their decision to deviate from their original act. Osbourne agreed, saying she was "very disappointed."
Morgan also used the buzzer on Kevin Colis for his rendition of "Rhythm of Love" by the Plain White T's. "For me, that just wasn't good enough," he said of the vocal and guitar performance.
"It was very sweet, very nice, but bland and forgettable," said Osbourne.
"I don't think you're up to par with the rest," Mandel said.
Zuma Zuma, the Kenyan acrobatic crew, and Matt Whilhelm, who performs tricks on his bicycle, also fell out of favor with the judges this week for showing no improvement from their previous appearances.
However, it is America's votes that determine which five acts will move on to the top ten – and one step closer to the grand prize of $1 million and a show in Vegas.
