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.

Here are the lyrics for you to read to see if it is the song you are thinking of: KENNY CHESNEY - A LOT OF THINGS DIFFERENT LYRICS (http://www.sing365.com/music/lyric.nsf/a-lot-of-things-different-lyrics-kenny-chesney/537962010c9a2acb48256ba40011bebc)
