Electronic Arts just released two PS4 themes inspired by Need for Speed: Most Wanted, both on the North American and on the European PSN.
Funnily, the European version is free, while the North American one costs $0.01 each. Of course, nothing stops you to get them on an European account, and then use them on your North American one (as long as they both have your PS4 marked as primary).
Both themes are fully static, and don’t include custom music or sound effects, but if you like cars, you might appreciate them. Check out a few screenshots below.
