check logic's last and latest album no pressure
it's rap, good flows and good vibes
if you're not really into rap but more into the edm chill stuff, porter robinson is the guy
it's edm, but not the Skrillex edm kinda shit.
really recommend his worlds album
if you don't like the edm style and really love the chill type of music, Sweet Dove is dope !
It's very emotional, chill, relaxed, and super ideal for studying
If you're into the chill type of music but actually with vocals, I'll recommend some that is quite similar to wallows:
cuco, boy pablo, tyler the creator
