Sure, age is just a number, but you have to admit that it's pretty impressive when young singers turn into country music superstars before they're old enough to drink, buy cigarettes, have kids and be considered 'mature adults.' Who do you think is the best country under the age of 30?

In today's readers poll, we've included some of the genre's freshest faces, including 28-year-old Miranda Lambert, Taylor Swift (22), Brantley Gilbert (27), Carrie Underwood (29) and Scotty McCreery, who is the youngest in the group at an impressive 18 years old. It goes without mentioning that there are loads of other great country artists under 30, but for the sake of simplicity, we've kept the choices at just these 5 to pick from.
