Wav files destination?

Noob here. I purchased some premium songs from the site. Downloaded BBM so I can add them to my card. There are two file types in the songs. I loaded the .sng files onto my sd card, but I am confused where to put the .wav files. The songs showed up and played fine, but the drum set was not correct. I looked in all of the folders and it didn’t make sense to where I should save the wav files.


The waves files is only for the accent hits .
