I think Adam Curry is the first person that I heard coin the term “sound track of your life.” Curry uses the term in referring to the songs that you remember at the milestone moments of your life. The sound track of your life relates songs with memories, and a musical group known as Bluebrain has done something similar by associating music with locations.
Bluebrain’s album titled The National Mall is an iPhone app that uses GPS to identify your location in the Washington DC National Mall and plays different songs based on the location. The band is working on two other albums/apps, one for Brooklyn’s Prospect Park and another for California’s Highway 1. I think this is a really cool idea for listeners and musicians.
For listeners albums like this will tie a song to a location that creates a memory, and for musicians this creates a new form of artistic expression by creating music that is right for a given location. While in the past you could buy album’s like Simon & Garfunkel’s Concert In Central Park, in the future you might by Ben Fold’s Tour Of Central Park.
