Every songwriter I know keeps a record of the songs they've written. Whether it be in a notebook or on the PC, these songs are usually accompanied by other information like chord progressions, tabs, and sometimes a simple mp3 file.
I wanted a way to organize this information myself, and figured there would be a lot of people in my exact situation. With that, the idea for JamJunky was born.
