Not bad, not great.
I know that there is a lot of build up in the Trance genre and that the same tune gets repeated a lot, but seriously, I thought whole song was looping until I checked to see that it was just ending.
I am not trying to be mean. The song builds up a lot, but the whole melody or background or something just isn't different enough. Something needs to change as the song progresses.
Or another possibility is that things changed too fast and the song ended up feeling like a loop inside of itself since there were only so many ways to make a tune different but the same.
Man, I hope this makes sense.
Anyways, it wasn't bad, it wasn't great, but it was good.
