Pop-Soul is soul music that has been polished slightly and given a commercially viable, crossover production. The vocals are still raw, but the material and the sound of the record could easily fit onto pop radio stations' playlists. Motown was the pioneering label of pop-soul, and through much of the '60s, it was one of the most popular pop music genres. In the '70s, pop-soul became slicker, and it eventually metamorphosed into disco.
