The Emotion Engine is an attempt at classifying songs using non-calculable data.

Whereas we can classify songs using it's metadata (amount of comments, styles, likes, ...) we have no way of using it's actual content.
This is where the Emotion Engine kicks in.


When you add (or edit), you song on the site, you can enable the Emotion Engine.
You'll be presented with 3 sliders.
One is the Polarity , another the Emotion, and the last one is speed.
You basically adjust them to what seems the more correct in regard to your song.

Using those values, our Emotion Engine will then calculate a color for your song. You can see that color on the Muzik Page and on the detail of your song.


Putting a color on your song allows our Recommendation engine to find similar songs based on content and not on simple stats.

Putting "random" data in the Emotion Engine will make your track appear as a suggestion for tracks that obviously don't match, meaning it'll get heard, but by probably not the right audience, usually resulting in negative votes.

Glad you asked that question..

Recommendations are a complicated thing, that are calculated once a day (takes a while).

What it takes into account

* Songs liked by users who also like your song
* Songs with similar colors (with certain conditions)
* songs with a high rating in the same genre (only used if not enough data to find a recommendation)


The process is still being updated with new parameters being tryed out. Especially to avoid forming recommendation circles.
