PLEASE ANSWER! 10PTS!A song for when you want him to be happy?

I usally get over guys really quickly, but this one guy i never got over. We are really good friends and he'll even tell me some of his secrets. But he doesnt see me as a girl friend, only as a best friend. I realized after a long time that i think nothing is gonna happen. I wish he was with me, but most of all i want him to be happy thats what i care most about. Many people recommend taylor Swift- and shes my favorite singer, but please not her because i already listen to all her songs. So maybe like P!nk, Kelly Clarkson, **Colbie Callet, someone like that. Thanks guys!!:(
