Here is a cool new tool that lets you make your own Google Maps + iTunes mashup. Movetracks lets you create playlists (or "Movetracks") based on your geographic location and a drive you are planning to take:
Here is a description that was posted on the Playlist Magazine Forum:
"..How does it work? When you visit the site, your iTunes library will magically appear on the left side of the screen. On the right side of the screen, you'll see the all familiar Google Maps application. Once your library has fully loaded, enter a starting and ending address and see your route populate on the map. Now, simply drag and drop songs from your library into the route you've created. Once you are done populating your route with songs, save your MoveTrack so that it's sent to your iTunes library as a playlist. Sync your iPod (or burn a CD), hop in your car and push play at your starting landmark. You are now listening to your MoveTrack."
MoveTracks will require Firefox and iTunes to be installed.
