ALL PRAISE YOUR SUPREME LORD CORBO
First off, I strongly recommend you to use a better hosting. There's tons of sites out there, you just have to google "file hosting" and they show up. Many of them don't have stupid bandwidth limitations nor they delete your files after 7 days. I downloaded your .wav at 42KB/s speed when I normally download at like 4 times that.
Okay, now to the song,
You didn't get anything "perfect". Don't be pretentious, specially when before saying you got something perfect you also said you suck at the both an only things that you're doing here, playing the guitar and singing.
The time is so wrong. I would have understood if it was deliberately on purpose a faster time but you didn't keep up with it. There was no continuance.
The song is waaaay much slower, and I am not saying that you're going to be limited by so, who knows maybe making fast arrangements of the song might actually work well and they probably have been done before, you just didn't do it right.
You "ate" several of the piano notes that you assumed you got perfect plus there is a "contra tiempo" (that's in spanish) but I guess that in english it would be "back beat" in the introduction that you missed.
My personal recommendation would be breaking your guitar and killing yourself.
Naaah, just kidding. My recommendation would be to keep the song's time. It will be pontentially easier for you that you're still learning to play guitar (assuming that's why you suck). If you want to make some improvisations and arrangements it will also be easier for you to do them.
Note that I'm not saying duplicate the song, in the end, making a cover is not about playing the song you've heard and the song every one knows the way it is. Making a cover is about interpreting the song, abstracting the meaning of it and representing it your own way, you have to fully understand what the song is about before jumping on and grabbing a guitar and play it, in my very humble and personal opinion, I'm not saying you don't but I'm telling you the way it should be.
Know that the song is about humanity's sickness, just to say something. And it is to express the problems and trying to make a change for them. The song could take several paths from the original concept but it took the one of being a somewhat calm and relaxing song that can make you cry or expresses the feeling of sadness.
On a more technical aproach, you need to make the notes sound. The notes hear cut and the sound mutes and it's a complete mess. Holding the notes more will also be aided by keeping the song's time.
fuck you all
