如何将歌曲从Windows手机音乐库复制到应用程序的独立存储空间？

我需要将每首歌转换为wav文件格式。

编辑1：我试过这个

private async void ImportMediaLibrary()
{
    try
    {
        var sourceFile = await Package.Current.InstalledLocation
            .GetFileAsync("Music/05 Beat It.mp3");
        CopyFileIntoIsoStore(sourceFile);
    }
    catch (Exception e)
    {
        System.Diagnostics.Debug.WriteLine(e.Message+"\n"+e.StackTrace);
    }
}

private async void CopyFileIntoIsoStore(StorageFile sourceFile)
{
    using (var s = await sourceFile.OpenReadAsync())
    using (var dr = new DataReader(s))
    using (var isoStore = IsolatedStorageFile.GetUserStoreForApplication())
    using (var targetFile = isoStore.CreateFile(sourceFile.Name))
    {
        var data = new byte[s.Size];
        await dr.LoadAsync((uint)s.Size);
        dr.ReadBytes(data);
        targetFile.Write(data, 0, data.Length);
    }
}

但我有这个错误：

Value does not fall within the expected range.

但该文件位于正确的位置...我想从Music文件夹中导入所有文件，而不提供任何路径，例如"Music/05 Beat It.mp3"

将文件导入Isostore WP8
