Song meaning of U Don't Have to Call by Usher

Oh, Usher, the true playa for real! This song is an anthem for all those guys who have had enough of their clingy girlfriends. Usher starts off by giving a warning to all the fellas out there, telling them not to leave their girl around him because he's a true playa. And who does he call upon for backup? None other than his boy Pharrell, who probably has a collection of hats big enough to make anyone weak at the knees. Usher then proceeds to explain that situations will arise in relationships, but you gotta be smart about it. Apparently, celebrating with the guys is considered a sacrifice in Usher's world, because he knows his girl can't sleep without him by her side. But wait, there's more! Usher's face is saying, "Why?" and there are tears in his eyes, because he's realized that he should have been more smart about it. *Insert eye roll here* He finally admits that he loved his girl, thought the world of her, but she just keeps leaving. Well, guess what Usher? She ain't gotta call! It's okay, girl, because he's gonna be alright tonight. And by alright, he means boogieing and partying like a single man should. No more waiting at home for love, Usher's gonna do what a single man does best - have some fun! So, ladies, no need to call him, he's quite fine without you. Bye bye now!
