I think the most significant moment of their carrer was when the boys finnaly got free from Lou, and since then they became even more special. That means a lot for them, and criate a lot of opportunities for them, reflecting on their careers, and way of making music. This is also a way to face a career, and to handle great responsibilities and important moments like Kevin's exit, for example. That is, this moment was one of the most important in my opinion, because it opened a new path of success and greater recognition for the backstreet boys.

and for me, as a Brazilian fan, every moment that they decide to come here is a moment more than important and memorable.

I believe their most significant moment was the release of "I want it that way" as a single and the Millennium album. They dominated the charts in all categories. Both the song and album really propelled them onto the music scene in a huge way, even though they were very successful with their first album. I want it that way will be a song to remember for the ages. Most people of any age know the words; now that's what I call awesomeness! Love my boys!

After watching their documentary "Show 'Em What Your Made Of" (which was excellent) it gave me so much insight into what they have gone through and what they go through in both their personal and work life. One defining moment I realized was when they broke away from "Producer" Lou Perlman. Granted, he did "manufacture" the band as AJ stated and we could all thank him for that but the fraud and money he stole from them throughout the years landed him where I believe he belonged - in prison. I think that was a big turning point for the boys - even if it did not change over night. When Kevin came back and they decided to finance themselves for the Show Em What Your Made Of album.... I believe this cause and effect helped change their lives and be able to live it the way they do today. I applaud them for making it through those hard times and for staying together. It was a tough but a learning experience we all have to go through in life. I am just so happy for them and for us fans that they stuck it out!

Getting recognition overseas when they first started out as a group 24 years ago. I believe they had many special significant moments but this one deserves notice because that moment opened up the path to their career. (:

Whenever any of the boys were dealing with personl issues. Why? It reflected in the music. Their passion and weaknesses and triumph flowed through their lyrics. And it made them even more relatable. (show me the meaning of being lonely, incomplete.. To name a few)
