At the end of each week, #Top40Tweets lists a cross-section of artists on the current pop charts and puts their tweets on display (along with their current chart number) for your enjoyment/scrutiny. This week, we look at 5 artists on the Billboard Music Charts. Guest Tweetmaster: Dave Hodgson.

#7 (Billboard 200): 2 Chainz – Based on a T.R.U. Story

Simple typo, or a subtle jab at his chef’s less-than-liberal portion of shrimp? You be the judge.

FUN FACT: 2 Chainz received a whopping 13 nominations for this year’s BET Awards. That’s 6.5 nominations per chain!

#1 (Social 50): Psy

He’s also the guy called “Dumbass,” “I Hate That Guy,” and simply, “The Piece of Shit.”

FUN FACT: Psy recently made an appearance on “Ellen,” and taught both Degeneres and guest Britney Spears how to do his famous horse dance.

#1/#2 (Digital Songs): Taylor Swift – “We Are Never Ever Getting Back Together”/”Ronan”

Spending time in Saskatchewan will make anyone re-evaluate themselves, Tay.

FUN FACT: Swift’s latest chart-topper, “Ronan,” is a charity single written about a 4-year-old boy who passed away from cancer, with all proceeds going to cancer-related charities.

#31 (Billboard 200): Chris Brown – Fortune

When you’re 15, you have to doodle this kind of crap on the top of your desk when the math teacher isn’t looking. But when you’re Chris Brown, you can paint it two stories high.

FUN FACT: Chris Brown has somehow not been drummed out of the music industry by now!

#1 (Billboard 200): Matchbox Twenty – North

Well, the joke’s on you. When you do concerts, you have to play Matchbox Twenty songs!

FUN FACT: In 2000, the band announced that the official spelling and capitalization of their name is “matchbox twenty.” You know, just to be insufferable.
