Last week singer-songwriter and dubious indie sensation Lana Del Rey told Australian Vogue that film work is her "happy place" and that she plans to make the transition into writing for film and "stay there." Whether this means she will stop making music or not is anyone's guess and whether that's a good or bad thing rests on your appreciation of disastrous SNL performances. I'm not going to make that judgment here.
One of the main inspirations for being a songwriter in the first place is a desire to tell your story or the stories of others through the art of poetry and song. So it should come as no surprise that many of the great in musical minds who brought you epic tales through their soul-stirring ballads (and Lana Del Rey) would want to try their hand at writing stories in other forms as well. It should also come as no surprise that the people who have made this jump have had wildly divergent levels of success.
