Radiounica was a Spanish radio station that operated from 1999 to 2001 under the ownership of the media group Prisa Radio. It was focused on broadcasting music in Spanish and targeted a primarily young audience, promoting a wide range of genres, including pop and rock. The station struggled to gain significant market share against competitors and was ultimately discontinued. Following its closure, its frequencies were repurposed for other Prisa Radio projects, such as Máxima FM and other specialized stations.
