But, Twain added, compiling her new "Greatest Hits" album has given her a chance to get some perspective on what she's accomplished in the last 11 years.
"I think maybe it's helped me appreciate everything that's happened up 'til now a little more," the Canadian-born singer said. "It's difficult for me to be objective, and it's difficult for me to look at things, to reflect, cause I'm so wrapped up in it all the time. It's really difficult to go Wow, this is kinda fun and kinda neat' and to revel in it a little bit."
Twain's "Greatest Hits" features 17 singles and three new songs; one of those, "Party For Two," appears in two versions -- one with Billy Currington for the country market, another with Sugar Ray's Mark McGrath for the pop market.
Twain is among the performers at the 38th annual Country Music Association Awards Tuesday in Nashville. The ceremony airs at 8 p.m. EST on CBS.
