6. The subject matter is obviously sad but apart from the intro, the music itself doesn't sound sad (and it's not like those arpeggios help anything). Call me emotionless if you want but Disappear doesn't make me sad at all. I've heard many sadder songs, even from DT - Wait for Sleep, Space-Dye Vest, Through Her Eyes, Vacant, Far from Heaven and Beneath the Surface come to mind.
