Scientists have discovered that babies can follow a rhythm. According to the study, rocking out is innate and unique to humans, with music being closely related to how young children learn about the world. I guess it's only a matter of time until infant rock bands start popping up.

I'd also wager that there are at least a few babies on the planet who are better at the guitar than Lil' Wayne, who now fancies himself a rock star. The first track from his foray into rap-rock ("Prom Queen") leaked last weekend, and it's worse than it sounds. The guitar parts on the studio version were obviously not recorded by Weezy himself -- he's hard-pressed to even hold a guitar properly -- though ex-Limp Bizkit guitarist Wes Borland or someone with equally mundane axe chops could easily have contributed the track's hackneyed riffing. Wayne adds some Auto-Tuned moaning and the recipe for an awful song is complete.

The whole "either this is a joke, or he's completely lost his marbles" thing seems to be en vogue these days, too. It was big news when Joaquin Phoenix, formerly known for his superb acting in movies like Walk the Line, decided to leave Hollywood to pursue a music career. Now, he appears to be trying to fill the void Lil' Wayne intends to leave in the hip-hop world. As Rolling Stone notes, he looks more like Jim Morrison than a rapper. Here's hoping for Phoenix's sake, and the world's, that he's just kidding.
