Over the years, on mundane, mediocre days, Leo Kottke's version of Fleetwood Mac's "World Turning" has come to mind. Kottke gives the tune a stark, bleak feel on the guitar and in the vocals, while keeping the listener's toes tapping with an infectious, uptempo beat. That fitting combination acknowledges a so-so day, but it's also a pick-me-up.
That's a savvy trick to pull off.
