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.

(Uncharted): Josh Groban – Hidden Away

Josh is making a rather timely reference to Kanye West’s Twitter-admission that he wrote the song “Perfect Bitch” about Kim Kardashian. It’s not the first time Josh Groban has riffed on Kanye’s Twitter presence.

FUN FACT: Josh is venturing into the wine business. Through a partnership with Mondavi Winery, Groban will release his own personal vintage some time next year. Nothing pairs with a classical vocal album better than a nice Cabernet sauvignon, am I right, wine fans?! [crickets]

(Uncharted): Justin Timberlake – My Love

Imagine how pissed everyone would be if Usain Bolt just decided to stop running after the London olympics, and focussed all of his energy on water polo. BECAUSE THAT’S ESSENTIALLY WHAT J.T. DID WITH HIS MUSIC CAREER.

FUN FACT: We were all in a tizzy when we heard that Justin Timberlake might be making music again. When we later found out that it was just a misunderstanding, we were so, so sad about it.

(Uncharted): Afrojack – Take Over Control feat. Eva Simmons

I dunno, maybe you could buy one of those t-shirt guns you see at sporting events, and fire it directly at all of those bare chested, roided-out EDM bros who get too riled up at your shows, you know, to stun them.

FUN FACT: Afrojack was recently listed at #9 on the Forbes list of the highest earning DJs, pulling in $9 million last year. That’s mere pennies to his socialite heiress girlfriend Paris Hilton, though.

#17 (Rap Songs): Lil Wayne – My Homies Still

A pop shove-it down stairs is supposed to look like this:

But we’re pretty sure that when Wayne did it, it looked something like this:

FUN FACT: Lil Wayne recently said he was going to take a break from rapping to focus on skateboarding. Hey, at least he’s not trying to play the guitar anymore.

#35: Wiz Khalifa – Work Hard, Play Hard

Wiz went a little “after-school special” on us there, but really, that’s kind of a nice sentiment to be coming from one of the most popular rappers out there today.

FUN FACT: Also, that album cover is amazing. At least it’s not Wiz doing a tough-guy pose while wearing sunglasses, like every other rap release this year.
