```

MusicFiles.getAll({
    blured : true, // works only when 'cover' is set to true
    artist : true,
    duration : true, //default : true
    cover : false, //default : true,
    genre : true,
    title : true,
    cover : true,
    date : true,
    lyrics : true,
    comments : true
    minimumSongDuration : 10000 // get songs bigger than 10000 miliseconds duration,
    fields : ['title','albumTitle','genre','lyrics','artwork','duration'] // for iOs Version
},(error) => {
    alert("ERROR: " + error);
},(response) => {
    alert(JSON.stringify(response));
});

//In order to get blocks of songs, for fix performance issues at least in Android, use next

componentWillMount() {
    DeviceEventEmitter.addListener(
        'onBatchReceived',
        (params) => {
            this.setState({songs : [
                ...this.state.songs,
                ...params.batch
            ]});
        }
    )
}

componentDidMount(){
        MusicFiles.getAll({
            id : true,
            blured : false,
            artist : true,
            duration : true, //default : true
            cover : true, //default : true,
            title : true,
            cover : true,
            date : true,
            lyrics : true,
            batchNumber : 5, //get 5 songs per batch
            minimumSongDuration : 10000, //in miliseconds,
            fields : ['title','artwork','duration','artist','genre','lyrics','albumTitle']
        });
}

```

MusicFiles returns an array of objects where you can loop, something like this.

```
[
  {
    id : 1,
    title : "La danza del fuego",
    author : "Mago de Oz",
    album : "Finisterra",
    genre : "Folk",
    duration : 132132312321, // miliseconds
    cover : "file:///sdcard/0/123.png",
    blur : "file:///sdcard/0/123-blur.png", //Will come null if createBLur is set to false
    path : "/sdcard/0/la-danza-del-fuego.mp3",
    date : "2017",
    lyrics : "[00:00] Cuando despiertes un dia..."
  }
]
```
