you need better speakers to hear it

It is almost as if you used really high quality headphones to make this. The whole beat is bass, and since I have crappy speakers, I had to turn them up really high to hear it.

This can be improved.

Well, for your first attempt at creating a song, I'd say it was good. The song has a pretty "underground" feeling, I believe this was your intention (no wonder why it's called "The Sewer"). I liked the waterdrop effects that you put in the song, they were pretty good.

However, I found this song a little dull. The beat was the same all the time. There were very little effects throughout the song. Basically, you could mute your speakers for a while, unmute them, and it would be the same.

You need to add some variations to the beat, along with some effects. This isn't a bad song, but it has a lot to be improved on.

Different

Ha this gets a little repetitive but I like the idea/concept. Well done.
Give my music a listen and rating too, thanks!
