With a CSCW perspective the activity of sharing music is an interesting leisure activity. It is pursued in a variety of forms, from the simple ways, such as physically handing over a record to a friend, to making digitally encoded music files available to unacquainted users through large-scale Internet peer-to-peer systems. However, we are interested in the sharing experience that takes place when jointly listening to music. Is it possible to transpose this kind of sharing to the situation of brief meetings that occur among unacquainted people on the roads? Would a tool like that make road use more enjoyable?

SoundPryer is an application designed for sharing music experiences between people in vehicles in the immediate surrounding. This is accomplished by streaming MP3 files between nodes in an ad hoc network. Since the application is based on handheld computers, the usage of the tool is accommodated in a wide variety of settings.
