Radiooooo is an interactive map that provides the listener with a song from the crowd-sourced “radio,” using a specified country and decade after 1900. The map allows the listener to specify whether the song is slow, fast, or weird and then suprises them with a selection. The map’s focus on the 20th century music was chosen to show the diversification of musical taste after the invention of the radio. The site’s accessibility and its presentation should be especially appreciated — it is clearly appealing, and serves as a clear example of a resource useful for any audience. This map uses well what Bethany Nowviskie describes as “wise foolishness,” as it plays with the user, opening up the world of exploration in popular music throughout the 20th century.
