The King had a slew of #1's in the 90's and haven't seen him mentioned yet. Pretty much tells me all I need to know about the country music selections on here. Some aren't so bad...others are downright awful...much like Richie's beer choices.
Brooks & Dunn are fine...they don't have any "best" anything beside their name, however.
Way too many in the era to name a best, although the ladies of the 90's were stellar too and can't be forgotten. Shania was a fix.
Clint Black is definitely not underrated...he is upper tier of country male vocalists.
Definition of underrated is...
And for you IPA enthusiasts...this is a keeper for the outdoor summer heat...
