I like the parallel structure to the lyrics. I think you kept the arrangement full enough with the heavy dose of effects on the bass and vocals (although the vocals are a bit metallic-sounding) and the judicious use of the nice backing vocals coming in here and there. I don’t love the melody for the “ha pasado…” line, which seemed almost random the first few times I listened to this--after getting it into my head, it made more sense, but it was hard to sort out what you were going for phrasing-wise there. I think that might be due to a combination of imprecise performance and the delay on those lines making them sound kind of messy, it’s a cool melody line but a bit hard to decipher on first listen. I do like the melancholy, melodramatic mood of the vocals, but this song dragged for me after a bit.
