In 1980, the Sony Walkman cassette player revolutionized music listening, turning it into a mobile, personal experience. The Walkman has largely lost its cachet in the MP3 era—eclipsed by the iPod and iPhone—but Sony is aiming to bring some of the Walkman's mojo back with a high-end player. The Walkman ZX2, set to launch this spring, has a powerful processor that will allow it to play high-res audio similar to that which will be available from Neil Young's Pono player. The price? Just $1,199.99. (Pitchfork)

In other tech news, Beats Electronics is being sued by a company called Monster in a lawsuit that alleges Social-Network-like backstabbing and duplicity. Here's the (relatively) short version of the story: Monster, an electronics company, partnered with Beats to design the headphones that became wildly popular—and, ultimately, made Beats co-founders Dr. Dre and Jimmy Iovine outrageously wealthy when Beats was acquired by Apple last year. Beats dumped Monster back in 2012, and after various shifts in ownership, when the lucrative Apple deal went down Dre and Iovine came out on top—while Monster was left in the cold. The question now is whether those shifts in ownership were merely shrewd business moves on the part of the Beats team, or whether they involved illegally fraudulent activity. This lawsuit will probably become the basis of a TV miniseries in a few years, so you may want to head over to Gizmodo now and bone up on the details of the unfolding case.

Finally, a few musician relationship updates—er, rumors:

• John Mayer and Katy Perry seem to be canoodling again. (Defamer)

• This probably won't do anything to cool Perry's ongoing feud with Mayer's ex Taylor Swift, especially since rumors that Swift wants to date Bradley Cooper seem to be false. (Billboard)

• Chris Martin and Jennifer Lawrence, who also supposedly aren't dating, went out together on New Year's Eve and had sushi, so there's that. (Bustle)
