Audio meisters Harman/Kardon make getting lost with Googlemaps a little more bearable with their Amplified Journey routeplanner/playlist generator. The web-based programme not only plots your route but picks the songs to go with it depending on your music tastes. Choose from a slightly limited genre list including Rock, Pop, Metal or even Opera and every leg of your journey will have the soundtrack to accompany it.
Each journey gives you a choice of 3 playlists perfectly timed for your journey based on the direction you're travelling, places or landmarks along the way. So on our test route of London to Scarborough, we found ourselves swamped with songs such as Hard Times in New York by Bob Dylan and New York City by T Rex while we were driving through the more sedate surroundings of York .
If you don't fancy the track, you can generate a similar suggestion Last.fm style. There are direct links to buy tracks or you can export your playlist directly to iTunes. Sure, it's not an essential driving accessory, but any playlist that starts off with In Your Park by Scorpions gets our vote.
