Which one brings a "Sadder" tune

I'm trying to get the ending to this right, but I'm not sure which one will feel perfect enough since it's more of a death song. So I need advice on which one brings more of a sad feeling, or what I could do to add more of a sad feeling.

IMO i think 4 and 1 sound more like a death song. i like really. may i have them on my ipod? D:


edit: no I think 4 is best.

 

Go ahead xD I don't mind, and thanks!

 

Promise 1, Promise 2, Promise 4
