My life till this very day, there is not much song that I could sing without lyric. But after some few thousands of repetition of certain songs for years,
I finally could remember some.
And it only could be done on songs that I really, really like.
There is this particular one song. That I finally could master after years. And every time I sing it whether in car or in karaoke. My subconscious mind, will saw her.
