Seasons Change.

Darker earlier in the evening. Darker longer in the morning. Yep. Summer is quickly turning into fall. Before you reach for your favorite seasonal disorder meds, consider two great things about the change of seasons: great new music and the opportunity to change the world.

Chances are you'll be switching on the lights in your house more often as we have less hours of daylight. But wait. Don't touch that light switch. At least not until you consider switching a bulb or two to Compact Fluorescent Light bulbs, affectionately know as CFLs. OK, I know. They aren't bright, they're too noisy, and they take too long to start up. These traits describe the CFLs of yesterday. CFLs have changed as much in seven years as digital music players and digital cameras. The technology and the impact it can have on the planet are nearly as sexy as my iPod. Think about this: if everyone of the 110 million households in the US were to change out just one traditional light bulb it would have the same greenhouse gas reducing impact of, get this, removing 1.3 million cars off the road. Read more about "How Many Light bulbs Does it Take to Change the World" in the September 2006 issue of Fast Company, www.fastcompany.com.

After you've switched out a few light bulbs, it will be time to dim all the lights and listen to some great new music. I grew up thinking that the cool new music released every three months or so is actually what made the seasons change. I still think it is. And the soon to happen summer to fall transition is no exception. I promise you won't be disappointed if you go directly to iTunes and listen to these songs:

I Don't Feel Like Dancin' by Scissor Sisters. If the Bee Gees and Elton John were to have a love child (could be interesting) it would sound like this. With hooks that will make you feel mighty real and maybe even make you feel like dancin', plus a songwriting credit shared with Elton John himself, this one can't miss and belongs on your iPod.

Waiting for The World to Change by John Mayer. Yep, he's adorable and fans throw intimate items at him on stage. Mayer is growing into a consistent pop songwriter. If Marvin Gaye were still around, he's a song he could have written for us. Instead, Mayer presents it as a candidate for the musical theme for the 2008 DNC Convention. Which will hopefully be held in Denver.

When You Were Young by The Killers. The hottie lead singer Brandon Flowers (no relation to Wayland Flowers of "Madame" fame) once said that he wants the Killers to be important and to last. Healthy self-esteem, huh? Anyway, here's great powerpop that sends props to the 80s. Great backing vocals, drums and even an old fashioned guitar solo in the bridge.

Like 'em? Buy 'em! Stealing is bad.
