Sounded like it should have been for a phone ring it sounded that good, but im not sure what song you were trying to make it sound like though, i know it wasnt the eminem song.
Hey, I like the harmony you used in this piece, but I think that it sounded too structured (since you used a computer to make the melody, instead of a keyboard). I also don't like how the rhythm got messed up after every phrase (every three measures or so). (You rushed into the next phrase by a coupel of beats.)
All of your other stuff is absolutely kick-ass, though. I love your new latin songs, and I'm going to download a couple to my iTunes. You're a great artist, and I hope to see your talent in full blossom in the future. Check out my first song (Cyborg Jesus Remix). It's goofy, because it's based on a flash cartoon, but I like the melody I put behind it. I'm going to be submitting some more stuff in the next couple of days, so keep an eye out!
Peace, and keep rockin'.
