)

func main() {
    mp3file, err := os.Open("/path/to/mp3/myMP3.mp3")
    if err != nil {
        panic(err)
    }

    // extract ID3v1.1 tags 
    mp3tags, err := id3v1.Getv1Tag(mp3file)
    if err != nil {
       panic(err)
    }

    // print all tags
    fmt.Printf("%+v",mp3tags)

    songname := mp3tags.SongName

	f, err := os.OpenFile("/path/to/file/myfile.mp3",os.O_WRONLY, os.ModePerm)
	if err != nil {
		panic(err)
	}
	defer f.Close()

    // create your tags struct
