His last song "Heavy" almost seemed like a foreshadowing of things to come. He was truly a musical genius, unfortunately, with genius often comes mental illness. I used to love their music, but a lot of it is quite dark. The song Faint is probably one of my favorite songs it seems to be more upbeat.
