Colton Dixon had only good things to say of Angie Miller. She sang a cover of Dixon's song "Never Gone" on Tuesday night's episode of "American Idol."

When Dixon, who finished in seventh place on the previous season of "American Idol," was asked to comment on Miller's performance he said, "Unbiased -- I really thought she killed it. She was really, really good. She just seems head over heels above everyone else. I was very impressed and thrilled that she chose that song."

That does not mean the 18-year-old singer-songwriter from Massachusetts didn't take creative license with the song. Her version of Colton Dixon's "Never Gone" was melodic and soulful.

"She did her own thing with it. In the first chorus, it almost had a little R&B flavor to it, which I really enjoyed," commented Dixon.

Dixon's fans have expressed their excitement over Miller's rendition as well.

"They love that it's stripped down, because the original version is definitely a rock power ballad," the original singer says of his fans. "I've even seen fans say she's competing for their favorite version of the song."

On Twitter Tuesday, Dixon posted to his Twitter account on Tuesday night, "@AngieAI12 just killed 'never gone.' I'm beyond proud."

Later in the night Miller tweeted a response to the praise from Colton Dixon, "Such a HUGE pleasure singing your song!! Hope you had a great night watching it!"

Colton says he first heard about Miller from her cover of "Never Gone" on YouTube a few months back and says the two have become friends since then.

"I commented on her video back then, telling her to keep it up," he says. "I had no idea she was going to be on Idol at that point."

Sales of Colton Dixon's original song skyrocketed after Miller's Tuesday night performance on "American Idol," to which he responded, "I'm going to have to thank her in person."

Currently Dixon's album A Messenger is No. 132 on Billboard.
