Judas is really underrated as a single.
Sure it's barely platinum in the US but the song was pretty big in Europe, charted top 10 in 27 countries and the music video has 190M views.
Most of my classmates liked the song and some hated it but still had the chorus stuck on their minds.
On another note the only person i know that knows Applause exists is my lesbian cousin that ocasionally bops to it
