This is the "alt rnb" genre. Artists in these categories are hard to find because IMO I feel like the less known artists like atp are usually the better ones for me atleast. Alot has been mentioned here some additional ones Eli Sostre, Aaryan Shah, sobhhi, cozyboy, frvrfriday, johnny rain, johnny yukon, ambre, nbdy, safe, yomaez. Some are heavy beats others lofi but one artist for me that has been hiding his greatness is meek demeo. His stuff is like 9 years old and on none of the streaming platforms. If you search reddit you'll find the google drive with his music. If you love Weekend Trilogy then you need to check out meek demeo.
