A new webapp from The Echo Nest not only provides directions for your next roadtrip, but also serves up a playlist of music filled with artists from the cities and towns you'll be driving through.
Called RoadTrip Mixtape, the serivce is powered by Google Maps (for the directions) and Rdio (for the tunes). It's potentially a great alternative to listening to "Boyfriend" again and again on local FM stations.
Though Lifehacker finds the service is "a lot of fun to use," it points out a pretty major failing: you can't (easily) export the playlists to take with you on your trip! But a rememdy -- in the form of a mobile version of RoadTrip Mixtape -- is reportedly on the way.
"In the meantime, it's a great way to choose some local music to listen to for your next trip, or just discover musicians who got their start in your area."
