honestly, i really wouldn't call this dubstep. It's probably more like a Trance song in my opinion.
Still a really good song.
8.5/10 is your score because: It's a good song, just not what the genre is. I'm also not a huge fan of Trance songs, but i will listen to them, especially if i'm giving a rating. As you stated in the description, it is a bit repetitive, but not just at the end. This next comment is not meant to be rude:
If you think this is dubstep, look at Xtrullor. Dubstep is one of my favorite genres, hence why i clicked on this song. I know you tried to make it emotional, but you actually took out most, if not, all of the dubstep parts. It's alright though. There is always room for improvement!!
So, your score again, is 8.5/10
