"Very technical, dry and repetitive"
This work is very much like an academic paper and the average listener will probably not enjoy listening, especially if you are not familiar with notes, chords, tempo and other music theory concepts. If you're looking for a technical and statistical analysis of the topic, then this might be useful to you. If you're looking for a narrative that examines the historical, social and cultural influences on development of R&B, you will be disappointed and bored.
The dry and repetitive narration is likely due in large part to the material, but it is dry and repetitive nonetheless. The narrator mispronounces the names of several of the more contemporary music groups.
