I wanted to post 'You For Me' as the song of the day, but the video for it on her channel is her sitting in front of the camera and singing it while accompanying herself on guitar. Something about her face sucks me in and makes it hard to concentrate on external things. So here's the link for it and you can just listen to the song in the background if you want to.
This is the song and video that I, along with many others, discovered her through. Made with the assistance of other YouTubers, it still makes me really happy.
