I Wake Up Screaming is a very early noir that has it's foot in the upbeat late 1930s. The title credits start with a bouncy tune and during the movie 'Over The Rainbow' plays in the background at the most un-opportune times. I mean The Wizard of Oz was only two years old at the time so I can't figure why that trademark song was used over and over again in this movie? If this had a more traditional and appropriate score the movie might have seemed more grounded in reality.

Turns out it was used simply because it was a popular tune at the time, having nothing to do with the "Oz" film. They also used "Street Scene" and "The Things I Love", which were also popular tunes of the day. Keep in mind, they had a minuscule budget for this picture...
