Tom Sandoval took Simon Cowell's criticism "to heart" on America's Got Talent

Tom told TODAY: "I could always be improving."

Tom's performance actually received glowing feedback from all of the other judges, except Simon.

The music mogul said at the time: "For me, the vocals weren't great, Tom. I'm going to be honest with you.

"However, not everyone comes on this show to get a record deal. Sometimes, it's about being true to who you are."

Despite this, Tom still loves singing Take On Me .

He explained: "I remember when we first performed that song a couple of years back, we had to do it a half step lower, but eventually, I got comfortable enough with it where we put it back into its original key.

"And to me, that song means a lot because it has history. I have an emotional connection to it, so being able to hit that high note was an example of overcoming a huge hurdle for me."

Tom is refusing to get carried away on the show, insisting he won't look too far ahead.

The TV star said: "We're just taking it one performance at a time.

"I mean, there's still a long way to go with so many incredibly talented acts going up there. So to me, like I said before, winning it seems so far off to me."

Tom previously acknowledged that he has a "slim" chance of winning America's Got Talent.

Asked what winning the TV talent show would mean to him, Tom told E! News: "That would be crazy.

"That would be so amazing. Obviously, there's such a slim chance because of so many great acts out there, but I would obviously be so happy for the band and for myself."

Tom also admitted to feeling particularly nervous about Simon's feedback.

Tom said: "He's a legend. I mean they all are, but he definitely has his reputation of being brutally honest."
