Turn it down! ><
It's not bad, very repetitive though, but the volume is the main problem here. Your kick is getting very very distorted and muddy and this track is clipping all over the place. Your audio is being very badly damaged because of the volume you exported it at. If you don't know what clipping is, you should really check out this youtube video about the so called "loudness war". (and its wikipedia page as well) Since I'm not allowed to post html, just search in youtube "loudness war" and click on the first result. I don't mean to be harsh here but this is a major problem and proper mixing is essential if you ever want to progress with your music. (and this is the MOST important thing of all to know about mixing!) All you need to do is turn the volume down on the main channel to a reasonable level and re-export and it should be pretty much fixed.
