If buying Kurt Cobain's childhood home ($400,000) is a bit more of a purchase than you can afford to make as a Nirvana fan, instead consider crashing for a night in the L.A. apartment Cobain shared with Courtney Love in 1991 and 1992. It's on Airbnb, and as you can see, it was truly well-used by the grunge power couple. Interested occupants might want to book soon, though: as media attention on the apartment has increased over the past few days, the asking price per night has risen from an initially reported $150 to the current $290.

The Grateful Dead's five final shows are extremely sold-out, so capacity is now being expanded virtually: the shows will be broadcast in selected movie theaters, and will also be screened on pay-per-view TV. The pre-sale price for all five of this summer's broadcasts will be $79.95. (Rolling Stone)

Katy Perry has been rejected in a bid to trademark the image of the hapless "Left Shark" that became a meme after Perry's Super Bowl performance. Among the concerns of the U.S. trademark examiner who rejected Perry's application was that the "Left Shark" image she submitted didn't bear close enough resemblance to the actual Left Shark with which (whom?) she performed in January.

The shark has five gills, a full mouth with teeth and round eyes with eyelids; however, the drawing displays the mark as a stylized depiction of an upright shark in full front profile with no dorsal fin, two full pectoral fins and two legs and feet; the shark has three gills and the sharks mouth appears without teeth; the shark also has oval eyes without eyelids.

Mounting evidence suggests that Jay-Z's new Tidal streaming music service is failing spectacularly. Somehow, the debut of Tidal seems to have actually boosted downloads of its two principal competitors, Spotify and Pandora. (Mic.com)

The Libertines have tapped producer Jake Gosling (Ed Sheeran, One Direction) for their forthcoming reunion album. "We wanted someone who is getting their thing going, rather than someone who is just going to put us through their machine," said the band's Carl Barât. "This isn't a heritage band making a heritage album." (NME)

Supergroup Art of Anarchy was a "scam from the beginning," says Scott Weiland. The Stone Temple Pilot frontman is distancing himself from the group that also includes members of Guns N' Roses and Disturbed. Weiland says he was paid to participate in the group, and didn't even know the other band members' identities. (Rolling Stone)

Kirk Hammett of Metallica is looking for a lost iPhone containing 250 riffs he'd intended for the band's next album. He's "crushed" he didn't have a backup of the data, says the guitarist, who remembers only about eight of the riffs. (SPIN)

Did Chaka Khan forget the lyrics to "It's Raining Men," or was she just leaving the heavy lifting to her backup singers when she performed on Letterman? Decide for yourself:
