Due to product differentiation and targeting policies, radio stations applying the same music format may show distinct differences in their music offerings. This article contributes to the methodology and development of practical measures for the analysis of radio playlists. Drawing from Philip Napoli's model on the dimensions of diversity, the authors develop indicators that cover four components of musical diversity: origin, ownership, repetition, and epoch of music. To demonstrate the feasibility of these indicators, this article compares the music played by Finland’s three leading adult contemporary stations.

流行音乐电台有多样性吗？开发一种对广播播放列表进行定量分析的方法

由于产品差异化和定位政策的原因，应用相同音乐格式的电台可能会在其音乐产品上表现出明显的差异。本文有助于制定用于分析广播播放列表的实用措施的方法论和发展。借鉴菲利普那不勒斯关于多样性维度的模型，作者制定了涵盖音乐多样性四个组成部分的指标：起源、所有权、重复和音乐时代。为了证明这些指标的可行性，本文比较了芬兰三个领先的成人当代电台播放的音乐。
