Maaaaaaaan, I remember when they were ALL over the radio. I actually only recently found out they're still making music, and I got pretty excited when I realized. XD Seriously, they're still one of my all-time favorite bands. They just had the complete package: strong individual vocals, beautiful harmonies, good and meaningful lyrics, and an overall sound that sets them apart from every other band out there.
Also, I did some research after rediscovering them, and apparently the age difference between them was CRAZY when they first formed the band. Nick was only 12, while the oldest member, Kevin, was already over 20! That's wild, man.
