[TOMT] [SONG] Looking for a song that i only remember the MV

Hey guys, I'm looking for a song about 4-6 years old, electronic genre. As the title mention, i mostly only remember its MV which set place in a barren environment. The singer is a female, young, with eccentric clothes and hair. most of the song is her singing but around maybe 3/4 of the song there is a mesmerizing drop. Thanks for the help if anyone have any clue :) Sorry for the bad English
