Can't find country music song. In early 2000. Some people wouldn't do things different in their past, but I would. Some people wouldn't change their past, but I would.

Are you sure those are the exact words? There is a line from a song recorded by country musicians that sounds a lot like what you are looking for: "People say they wouldn't change a thing, even if they could Oh but I would." The title of that song is "A Lot of Things Different." Kenny Chesney recorded it as a single around 2002 and it hit #6 in the top ten chart in 2003. Before Chesney, Bill Anderson recorded it and included it in his album of the same name which was released in 2001.
