      @Nisha_R Are you sure the media file contains metadata ?
      I just tried this example and in onPressed, console.log(playMusic.metaData.title) printed the title as expected.

        @p3c0 i am sure the song contains the metadata because i have edited it online.
        could you please share the code you have worked on?

          @Nisha_R Thats strange. Try following:

          import QtQuick 2.6
          import QtMultimedia 5.6
          
          Item {
              width: 400
              height: 400
          
              Text {
                   text: "Click Me!";
                   font.pointSize: 24;
                   width: 150; height: 50;
          
                   MediaPlayer {
                       id: playMusic
                       source: "MySong.mp3"
                   }
                   MouseArea {
                       id: playArea
                       anchors.fill: parent
                       onPressed:  {
                           playMusic.play()
                           console.log(playMusic.metaData.title)
                           console.log(playMusic.metaData.albumTitle)
                           console.log(playMusic.metaData.genre)
                           console.log(playMusic.metaData.year)
                       }
                   }
               }
          }

                  @p3c0 ,
                  i had initially dumped the mp3 files in resources folder and tried to access those in my code.

                    @Nisha_R No. I meant to say the source url. What does it look like? Can you post it ? Checking if the url from resource is correct.

                      @p3c0 this is what i have given.
                      Audio {
                      id: playMusic
                      source: "qrc:/music/2.mp3;"
                      }
                      music being the folder in resources.

                        @Nisha_R Why the extra semicolon at the end in source ?
                        Does the Application Output show any errors ?

                          @p3c0 there is no error with respect to the semicolon .
                          setting its path with respect to resources shows undefined, but when its relative path is set the metadata is displayed.

                            @Nisha_R Did you try removing the semicolon ?
                            Also are you sure the file is present at the same location in the resource ?

                                @Nisha_R Does it play from resources ? Can you post a complete minimal example with this Audio element here?

                                  @p3c0 okay that will be helpful.

                                  MediaPlayer{
                                              id: player;

                                                  id: playlist
                                                  PlaylistItem { source: "qrc:/music/4.mp3"}
                                                  PlaylistItem { source: "qrc:/music/5.mp3"}
