I usually don't like reviews, but I had to review this one.
I didn't like the first :30 seconds. I think you should improve on that part.
I base on whether or not I'm going to listen to a song if it sounds interesting in the first :30 seconds, I know that is a bad habit but it's how I listen to songs. The first :30 seconds didn't impress me much so I was going to change it, but since you're Envy, I listened more. The rest was perfect.
