    @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"}
                                        }
