Lots of things happen in the music business and on the internet every week. This is an attempt to make sense of them. OK, here we go.

  • After months of speculation and taunts from Ryan Seacrest, the Twitter Music App is live and available to mere mortals. So far the verdict is… totally going to work! Or it’s… a work in progress! But what does it do exactly? According to Twitter’s blog, the app “uses Twitter activity, including Tweets and engagement, to detect and surface the most popular tracks and emerging artists.” You can listen to full songs by using your Rdio or Spotify account, or the app will direct you to iTunes if you’re looking to purchase a song. Wiz Khalifa seems to like it:

  • What effect will this Twitter music app have on iTunes sales? It’s tough to predict, but one things clear: business is booming. According to Billboard, the company continues to “dominate with a 63% unit share of the U.S. market for digital music downloads in the fourth quarter.” This good news for Apple and presumably good news for Wiz Khalifa.

  • Wiz Khalifa seems like a pleasant, affable guy, right? He’s someone you could probably hang out with, right? Someone you might want to tattoo on your arm, right? Yep, as MTV reports, it seems that Khalifa’s fiancé Amber Rose recently got the “Black And Yellow” rapper’s face tattooed on her arm. And, yes, this is what it looks like:

  • But it’s still better than this horrifying Thom Yorke tattoo. Can we give the tattoos a rest for a little bit? Where do we go from here? Grimes tattoo? Yes. Probably a Grimes tattoo.

  • As the tattoo industry continues to grow as people find new musicians to forever render on their flesh, the record store industry has seen better days. Though tomorrow is Record Store Day, one famous record store will not be open for business. As Brooklyn Vegan points out, Bleecker Bob’s closed up shop after 46 years.

  • If you haven’t checked out this Paul Stanley stage banter yet, please do.

  • Last week Jay-Z released his latest song/display-of-cool-dad-bravado, “Open Letter.” The song found Jay-Z inviting President Obama to “chill with me on the beach.” The intrepid reporters at Today have now debunked this claim. But they’ve only scratched the surface. Does President Obama like “Beach Chair,” that horrible song with Chris Martin off Kingdom Come? ANSWER ME MR. PRESIDENT!

  • Designer Storm Thorgerson, the man behind Pink Floyd’s legendary Dark Side Of The Moon album cover, died this week at the age of 69. Over at Pitchfork, writer Eric Harvey looks at Thorgerson’s legacy and examined some of his iconic covers.

  • This has been a tough week. Let’s all try to have a good weekend. Maybe start by listening to the new Daft Punk song for 10 hours.
