i agree, music needs to be heard....there should really be a tutorial function for the newbies mayn...
anyhow, go back to your post homes: click "modify" on the top right hand corner of your post, that will send you back into your post, were you can augment it accordingly...below the box were u type your post, you will see a button that reads "additional options"
click on that, and load your beat in there....Hope its FIRE OCTANE
