zaudio plugin

i noticed one of my members uploaded an mp3 into the website, so i decided to check it out. i noticed mini player didn't load, weird right? so i decided to download that mp3 and uploaded it myself. after that was done uploading, i looked at the mp3 i uploaded and the little player was there but not on my member's file page. are admins the only one able to get the little player or is there something wrong?
