I'll be brutally honest. Okay? Okay.
I really like what you did with the instruments. I really hate what you did with the vocals.
Basically, the instrumentation is a very nice update from the markedly 70's vibe of the original, you've added a lot of chaos to get that modern wall of sound... uh, sound, and I really appreciate that. I was a bit sceptical about the synth in the intro but I warmed to it, and nothing else about the score struck me as less than good.
But the vocals don't work for me at all. I might be wrong but I thought I heard a few false notes, and either way the whole thing is just too monotone - far too much of the actual melody is lost, I'm guessing because you (or whoever did the singing) lacks the range to hit the high notes. Now, I'm pretty sure you can rejig the melody to fit the voice of the vocalist - I guess that's what you were trying to do, and I appreciate the fact that a cover artist needs to bring his own interpretation to the song, but I definitely feel like you've lost too much of the melody. Plainly, the vocalist sings too few notes. More variation please
A striking resemblance to the Killers in the vocals, I might add.
