If you create the music you want to play with a 'tag' then you can stop the music using the tag.
I had the same problem where my title music continued playing when I went into the main game. So I set the audio to have a tag and stopped the audio playing by using the 'tag' name.
Hope this helps..
Thankyou for your help! It worked! <img src="smileys/smiley1.gif" border="0" align="middle" />
