I'm back,

I'm not popular but I know almost everyone, 
I'm not a nerd but I'm very smart,
I'm not a total gamer but I like to play,
I'm not a singer but I can sing,
I'm not a jock but I play sports.
Who am I.
 
A little riddle with a lot of correct answers, tell me who I am and get well me struggling to post a picture on imagur because my phone is a butt.
