Audio experts needed please read Thread

Hello and thank you for reading

I am trying to add custom sound tracks into the game senran kagura estival versus. I have been able to put them into the game and play them but they will not loop. I have tried a lot of programs and even asked a lot of people and no success has been obtained. I think it is a simple problem but if anyone is willing to give me any sort of information on the subject I would greatly appreciate it. Thank you again for reading.
