4. Hanson
They may have MMMbopp’ed their way into our consciousness but the talented and wholesome brothers Isaac, Taylor, and Zac would hold on to their fan base by capitalizing on their musical and writing skills. Now well past puberty, the trio cut their hair, got hitched, had babies, started their own independent label, and continue to play to their all grownup ”Fansons” on tour. Shout it out!
