I think is a good product because has the songs that I wanted in their original versions and I think is a goos idea to put together this songs from Luis Miguel was a child to his first greatest exits. Is like a "machine time" in the Luis Miguel's singer life. The quality of the sound is excellent. The only thing that I would like is a brief information about each song with for example, date of production, age of Luis Miguel at that time and the letter of the songs.
