Why: George Strait would make a list of the Top 5 country singers of all time, regardless of letter. Very few have been able to stretch a career out across 30-plus years without losing appeal to younger country music fans. His new music today stands up to his hits from the '80s and '90s. As he nears 60 No. 1 hits and his final year on the road, it's time to sit back and appreciate the legacy Strait has left behind.

Honorable Mentions: Taylor Swift, Hank Snow and Sugarland
