I thought this was a good song, but there was one major thing that annoyed me. It seemed like the audio was a tad too loud. It just came off as a tad screechy to me. It's still a nice song, because it shows you attempting to put a new kind of emotion in your song. Addiction is a sensitive subject, so it's good to know you can write about it. I appreciate this more for its message than what it actually has.
Let me say that you are an expert on changing your voice. The guitar parts might have been a tad too loud as well. My favorite part was probably at the end when it became softer. You manage to keep a good tone at least. It's amazing how many audio submissions you put here in one day.
