@Incinerator but something strange happened : the loop worked for the first music i injected , but strangely , it didn't worked for the second song that i injected , but appearently i did the same procedure whit both files , the music that the loop doesn't work for is the one i used to substitute "dark messenger" , while the one that the loop worked for is the one i substituted for "battle", and in both cases all i did was to add the two tags that you told me to add in the tagg section , so what may i did wrong ? :\, the only difference i notice is the length of the two loops , the working look belong to a song of 3:40 minutes , the not working loop belong to a 6:46 minutes , so maybe the problem can the the size of the loop , i don't know , what do you think ? :\
