The introduction (Youth) was very powerful, if you look at the color coded lyrics, it's also in Japanese but Rap Monster is talking about how Youth has no age. And just an album rewind on some of their best hits. And just a nice outcome. I really liked the remix of all the songs in one short introduction, they make everything work. I 100% suggest the album, whether you have the actual album or you stream it, Japanese versions usually sound more interesting then the Korean Originals. What are you waiting for, go stream Youth! :)
