Looking for a Story

I lost this story I wanna re-read. The story goes that this guy wanted to be a music star but failed causing his mother to work herself to death and his sister to never be able to pursue her dream of doing music, he blames himself and then dies. He goes back in time and decides to become a music producer and help his sister become a star. If anyone can tell me the name I would be Really glad. (づ￣ ³￣)づ
