Startup Idea: Music Organizer App for DJs

Startup idea to create software that sorts thousands of songs into preselected categories like genre, harmonic keys, and tempo. The software should also find and label individual tracks accordingly. This tool will allow DJs to save time and direct their creativity towards creating new mixes.

I am a part time DJ Organizing music by genres, Keys tempo, etc. A program that organizes all the thousands of songs into pre selected categories.

For example all the progressive house, bass and trance songs into a folder. and then sub folders based on harmonic keys, tempo and energy as well as find and label the individual tracks as such.

I would definitely pay for this kind of software. It would save a lot of time so I can experiment more with the different tracks and come up with something new and interesting the crowd would love.

Mixed in key is a software that finds the keys, energy level and tempo, but doesn't do it automatically and then doesn't sort out the tracks.
