A music system for a DJ that will make him happy :)

My suggestions are how to improve the experience of interacting with DJ programs, searching for music, preparing tracks for a DJ to make his life easier and make this experience more productive and enjoyable. A system that will allow the DJ to be more involved in what he does.

So, what does each DJ do?
1. Searching for music
2. Buys
3. Sorts music according to his personal system
4. Prepares, plans, creates a mix
5. Plays / records online or offline, posts in social networks

1. Music search
First of all, if we are talking about searching for music, I think the most convenient tool for me is Spotify
It can be system in Beatport or other streaming services when we get in separate folders tracks of artists and labels that are subscribed to
This is similar to what is done in Spotify, when we subscribe to an artist or playlist, we get new tracks in the playlist "radar" and "new discoveries" based on our preferences, the same system I believe should be organized in DJ programs using implemented streaming services.
That is, the DJ goes into the traktor, selects pre-prepared playlists (house, techno, breaks) to the left of the folder shows the number of new releases by artists and labels since his last listen, if the DJ likes something, he buys them directly into the Traktor
2. Buying music
I would very much like this feature, shopping directly in the Traktor program, as it is done in iTunes. Thanks to this method, we will get a convenient tool for searching for music in various streaming services, tracking our favorite artists, and quick purchases. It would be cool to click one " buy " button next to a track and that track would automatically upload to my music folder and become offline
3. Music management
After purchasing tracks, the DJ must have a powerful tool to manage his library, at least as in the rekordbox, all offers for the library are here

4. Planning
After the DJ has processed all the purchased music, he starts planning, composing a mix, this will help us with a separate type of playlist mix Planning, which I wrote about here

This is a special playlist that is not intended for storing music, but for perfomance.
5. Time for play mix
To publish our mixes, it would be good to have integration with soundcloud, mixcloud, kuvo from pioneer, iTunes, Spotify, and so on

If this unified system worked, I am sure that it would contribute to the development of DJing and make every DJ a little happier
