Simply Amazing
This is my first audio portal review, heck I don't think I should even write this one. I know very little about music and the appreciation of it. Therefore, apologies for any ignorance.
First of all, I respect your bravery for giving a serious attempt to do a cover of such a well-known song. I've heard several covers by even professional artists and most of them are mediocre at best. I personally am not a fan of the original version of the song and only truly appreciate the song when sung by a passionate group of people.
Also, I am a sucker for Orchestra music and the use of harmonies. The sounds of drums and strings can leave me in awe like the sight of Justin Bieber for a typical teenage girl (maybe I should leave that simile out). That combined with yours clear but powerful voice, managed to create the feeling that I mentioned that I could only experienced when sung by a crowd of people.
However with that being said, my favourite parts are actually the slightly more quiet parts of the song. I think you sound the best during the lower keys, especially the first minute of the start which captured my attention as I was jumping from song to song across the audio portal. Maybe it's because of your manly voice? xD
There's not really any criticism that I can honestly make, seeing that I know so little myself. As I'm writing this, I can only think of more praises for this song. Excellent choice of instruments to convey the emotions of the song, nice gradual build up, awesome voice... I could go on. Also, there's something wrong with your MIC? I still can't tell after re-listening to this song for at least 8 times by now.
Thanks for the treat. This is definitely the most professional cover I've ever heard. Congratulations on making a truly unique cover of an already exhausted song.
