On next Monday's All Songs Considered (Nov. 9), we'll talk about some of the developments, trends and memorable moments that helped define this decade. We'd love your help.

In the comments section below, tell us what moments, albums, artists, trends, or developments you think best defined the past decade. You can also tell us in a Tweet. I put a note up on Twitter with the hashtag #decade00 (a hash tag is the # sign followed by a term so it's easy to track what people are saying), so in a Tweet you could tell us what you think and put #decade00 at the end. You can see people's responses on Twitter below.
