Identify a song

[Mad Melvin]

This is a long shot, but fudge it. I was eating at an american style restaurant the other day. There was some music in the background, mainly classic american rock songs and a few newer ones. The one song that caught my attention was not rock. More like country-ish. It had bass, drums and acoustic strumming, with a female singer. The song had no lyrics, it was all humming and shit. It was mid-tempo, melancholic song with a pretty melody. I just can't remember the melody anymore. Just that I really liked it. This is really driving me nuts.
