It isn't enough that they're famous. And rich. And beautiful. And have pretty successful careers already. No, there are some actresses who really, really want to sing. Should they? Well, that's another question, and with Scarlett Johansson set to become the next actress looking to sing her way into your heart, we size up some recent crossover efforts:

' Anywhere I Lay My Head '
Deeply compressed low baritone—like Scarlett was 20 feet from the mike. But it's an album of Tom Waits covers, so she gets points for being cool.

' Seastories '
Alt-country influenced melodies with enough denim-jacket, raspy-edged appeal to make it a worthy soundtrack to a road trip.

' A Little More Personal (Raw) '
Who cares? It's the worst title of the bunch, and using the paparazzi chasing her as inspiration for her songs? No, thanks.

' Paris '
Paris Hilton's baby-talk speaking voice—but she's singing. Imagine a syringe full of Pixy Stix right to the bloodstream.
