Time flies when you're rocking. It seems like yesterday that some of our favorite musicians were just babyfaced rockers just making a name for themselves. Some of them have aged gracefully.

There are also rockers who were well established during the 21st Century's first decade, and while some may show a little more wear after plenty of miles traveled, others somehow have found the secret of youth and don't appear to have aged a day.

In honor of the viral How Hard Did Aging Hit You Challenge, we decided to see how some of our favorite artists have aged throughout the years. So join us as we take this pictorial look back with some of your favorite

musicians and how they looked during the 2000s as opposed to how they look now.
