I first started liking the Backstreet Boys during the Backstreet's Back era. At that time Kevin was my favorite Backstreet Boy because he was the mature, tall, dark haired and gorgeous one, lol. My favorite song used to be Everybody but now I love Incomplete and More Than That. Since becoming a fan, I have seen the guys on tour four times. My favorite tour was Unbreakable because I was front row, touched Nick's hand and had AJ's water thrown over me lol. The one song I wish they would perform in concert is Climbing The Walls and take out I'll Never Break Your Heart (as I'm not fussed on that song).
Nowadays, my favorite Backstreet Boy is Nick and Kevin because I'm glad Kevin came back and because Nick grew up and is hot (plus I love his voice and personality). I have to admit, at first I didn't think much of Howie but now he's really grown on me. I still don't give Brian much thought because I just don't have all that much interest in him or anything in common with him. If Nick were to leave the band, there is no way it could continue on as a foursome, but If I had to pick one of them to leave, I would choose Kevin because I already know they work well as a foursome without him, but I wouldn't want him to go again.
The one thing I love most about these boys is their genuine love for what they do. But if I could ask them to change one thing it would be come and tour in Wales, we are a country too!.
At the end of the day, we're all fans but the one thing that bugs me most about this fandom in general is the crazies. I think Howie is the most fan friendly where Nick (only because sometimes he's come across as uninterested on sound check videos I've seen) needs the most work. Regardless, I love these guys and will remain a fan forever unless they release crappy music and start treating the fans like crap too.
