Anyone know how to make this so that if album artist equals Various Artists then it will just put the song artist.
function pad(number, length) {
      var str = '' + number; 
      while (str.length < length) {  
          str = '0' + str;
      }
      return str;
  }
 
 function ifnotempty(value,sep){
     return value.length > 0 ? value + sep : '';
 }
 
 function ifnotempty2(value1,value2,sep){
     return value1.length > 0 ? value1 + sep :value2.length > 0 ? value2 + sep:'' ;
 }
 
 ifnotempty2(albumartist,artist,' - ') + ifnotempty(album,' - ') + ifnotempty(pad(trackno,2),' - ') + title
