What in your opinion makes a piece of music an outstanding track ?

[GlitchedSalvation]

The lyrics (if existing) should be at the very least somewhat poetic, and the melody should fit with the accompaniment (I'm looking at you, Cubicles). Sticking with the melody, if there are vocals, they should fit the singer's vocal type. If no lyrics are present, it should of course have a main feeling, but more delicate undertones. (sorry if it's confusing)
