But it's not as easy as it seems, you have to choose the arrangement, lyrics that fit and a natural perception of the sound of the time. I usually use key dates, it helps a lot, but the app gives you lots of choices, some good and many bad, let's say I put one little bit about my very specific musical taste, this also helps... thanks for commenting friend... I apologize for the poorly worked images, my focus at the moment is on the songs but I'm always trying to improve...
