Stop s1.loadSound(songName,false);

hey . simple question.

making my own .mp3 player and if a song it chosen, it is downloaded into the player by … s1.loadSound(songName,false);
now if a person changes his mind and wants a diff song , it seems the 1st loadSound keeps going in background, or maybe it dont, seems like it though =P
but if it does how do u stop it?

thanks
