If pop country wouldn't have gone so downhill I like to think someone would have covered this and made it big.
Honestly, I have no idea how popular some of these acts are any more, but Isakov and John Craigie are awesome and underappreciated. Here are a couple of my favorites from Craigie (the first is with Isakov):
I like the sounds of Isakov better, but I think Craigie has some really good lyrics. Isakov is pretty abstract, but Craigie does what I think is the ultimate for a song writer - say something that's fairly straightforward but do it in a pretty interesting way.
