(CBS) There's proably no one more excited about Sunday night's Grammy Awards than Taylor Swift, who's nominated eight times.

And, as "Early Show" co-anchor Julie Chen discovered when she sat down with Swift, the country superstar is still pinching herself.

"I am so completely living in this moment," she said. "I've had some time off to just look around and go, 'I cannot believe this.' "

Swift, Chen observed, is terrifically talented and only 20 years old. Amongothers, Swift is up for Grammys for her hit song and record, "You Belong With Me."

Swift said she was especially excited to be nominated for Album of the Year.

She said, "For me to have written those songs about personal experiences, songs that I've written, like, on my bedroom floor or when I woke up at 3 a.m., to have something that personal get nominated for Album of the Year, it just, it blows my mind."

Chen caught up with Swift while she was preparing a special "top secret" Grammy performance at a Los Angeles sound stage - the same one where "The Wizard of Oz" was filmed.

Soon, Chen pointed out, sound stages might be as familiar to Swift as recording studios. She's making her film debut next month in "Valentine's Day."

Chen said while with Swift on the sound stage, "It's amazing to think that this whole sound stage came to life, and the Yellow Brick Road was over here, and that's where the witch disappeared into the ground."

Swift responded, "Would it be shameless and cliché to say something like, 'I'm not in Nashville anymore'?"

However, the singer says she'll never stray too far from her country roots.

"Music is No. 1 for me," she said. "It's always going to be. Music is involuntary. Writing songs is something I have to do in order to be OK."

Swift said she doesn't know what it would be like to win a Grammy.

"To walk up on that stage and accept a Grammy, I would just, I would love to know what that felt like someday," she said, adding, "And I am not going to be picky about it."

"I would take any of the eight," she said. "I would take one this year or ten years from now. You know, it's just, it feels really wonderful to have eight shots at it."

You can see Taylor Swift perform live on Sunday night. The 52nd Annual Grammy Awards will air on CBS at 8 p.m./7 p.m. Central. Mary J. Blige and Andreas Bocelli will also sing a special duet of "Bridge Over Troubled Water" as part of Grammy's effort to raise money for the American Red Cross and their efforts in Haiti.
