Billie Eilish and Alec Benjamin give a dark feel with a light overtone. This often talks about random things often being much darker then expected (e.g. Bad Guy and Boy in the Bubble) For a very light feel talking about completely random things that can be dark but also meaningful, try out Bill Wurtz. (I’d recommend him to anyone but hey, he’s funny) Other artists similar to these musicians are AURORA, Melanie Martinez, and Lorde. Hope this needlessly long explanation helped!
