Chillwave is an electronic and often lofi genre of music whose artists are often characterized by their heavy use of effects processing, synthesizers, looping, sampling, and heavily filtered vocals with simple melodic lines.
The genre combines the larger 2000s trends towards 80s retro music and (in indie music) use of ambient sound, with modern pop, as in electropop, post-punk revival, psych-folk, nu gaze, and witch house.

There's some other good stuff on here too.
