Thanks to the amazing contributors of h1tchr (pronounced hitcher) there is now a website where you can find and contribute to user generated h1tchmaps of songs that sound similar or share certain commonalities like melody, beat or lyrics. You can also connect cover songs, and songs that contain samples. While other sites like soundsjustlike will compare two songs, h1tchr lets you make entire maps of music. Check it out here. h1tchr was created by David Pattillo founder of Bang Bang Boogaloo.
