json testing

Where can I find a pre-populated json file for testing?

I am building an application that can import JSON data, I want to test about 10k entries, and I don’t feel like building a JSON string with that many entries…. so does anyone have a location where I could find some generic populated JSON files? (Music Albums / Movie Listings / Animal Kingdom / Census data / Car Models… I’m not horribly picky, I just need some good data to test with.)
