theres a big diffrence,the soundpack in the download section was created by Bennico from the SI forums and was a big hit for FM10 and has been updated for Fm11 and has premier league team chants, trust me you will notice a big diffrence from the original boring match sounds,back up your original sounds folder and events folder and give it a try,if you dont like it then just go back to the original but i dont think you will,i deleted my version from here but its much the same except i had more chants from diffrent leagues on mine
