Hip hop soul is a subgenre of contemporary R&B music, most popular during the early and mid 1990s, which fuses R&B or soul singing with hip hop musical production. The subgenre had evolved from a previous R&B subgenre, new jack swing, which had incorporated hip-hop influences into R&B music. By contrast, hip hop soul is, as described in The Encyclopedia of African American Music, "quite literally soul singing over hip hop grooves".

Neo soul is a genre of popular music. As a term, it was coined by music industry entrepreneur Kedar Massenburg during the late 1990s to market and describe a style of music that emerged from soul and contemporary R&B. Heavily based in soul music, neo soul is distinguished by a less conventional sound than its contemporary R&B counterpart, with incorporated elements ranging from funk, jazz fusion, hip hop, and African music to pop, rock, and electronic music. It has been noted by music writers for its traditional R&B influences, conscious-driven lyrics, and strong female presence.
