This jazzy tune has some nice walking bass lines around the fretboard. Try this one if you are up for a challenge! It's easy when you break it down, but it's quick.
"I don't think I knew what depression was. I knew I felt funny sometimes and I was different. I think it's a musician thing. That's why I write music. You know, I'm not like some messed up person. There is a lot of people that suffer depression that don't have an outlet, you know what I mean? That can't pick up a guitar for an hour and feel better.” - Amy Winehouse
