I'm sorry,
look, I have garageband too, and just well, try and make it at least sound like you didn't slap a bunch of prefabs together please. I recognise every single note in this song, so it naturally sounds very poor. I believe you can do alot better, because for a first song, with that many prefabs, I would expect something completely horrible. Its ok, just try a little harder. I too use GB because I am too cheap to go out and buy something powerful like Reason, but there is no reason you can't put a little more time and effort into it, is there?
