If you upload a music with ' in the file title it will display as \' on frontend.
Here is the fix
go to /inc/classes/BxDoIShareMedia.php
find $ret .= $sPic.'<div class="shareMediaAdd"><a href="'.$sHref.'">'.$sTitle.'</a></div>'.$sShowRate.'</div>'; on line 806
replace $sTitle with stripslashes($sTitle) then you are all set.
