Today I was looking at youtube on my sisters old computer which she hasn't used for some time and I saw the name TFBOYS keep appearing when I was looking at the recomended for you, so I figured what the heck I 'll go check it out. They are SO cute. They debuted in 2013 at the ages 12 and 13,  now they are 16 and 15, there are three members. The group is Chinese. So I think you should look them up if your into the cute kinda thing, their music is prety good though. I recomend you listen to loved. Anyway that is my happiness for today. I personally think that when they sing some of their English lyrics it is more recognizable than older groups' English lyrics. Please pardon the spelling. :)
