Here's a few lovely ballads by women singers.
Tell Me I'm Crazy by Shelby Lynne
Someday Soon by Crystal Gail
or what about John Berry he's a master a ballads and too many to list but check out You and only You someone mentioned Vince Gill well your all right he is superb singer guitarist and is now a member of The Eagles now ya can't get much better than them!
One of my favorites, a Billy Joel tune that Garth remade and made it his own (in my honest opinion)
Garth Brooks - Shameless
Unfortunately, this isn't the original release from the early 90's. It's close, but not quite the same. I'm not sure if he remade it, or if one of the GH's in later years edited the music a bit. *shrug*
