CD Burning

I am trying to learn how to Burn CD's this is my question.
When you download a song their is a bleedin or background of talking like static you cannot get the music to come thru for all the other sounds that comein how do I keep the unwanted trash or static from coming. Thank You, Mary

Hope this is the right forum to ask this
P.S. _ I am using blubster to download my songs to media player, I am using Windows XP,
