SongKong also adds other measurements, that can be useful, only SongKong adds this data to your songs so there is no danger of replacing data added by other providers. The attributes give a probability of something rather than a definitive true or false answer in the range of 0 - 100. So for example the Instrumental attribute shows the probability of a song being totally instrumental, if the track had somebody introducing the track at the start the value would not be 100 but it would still be higher than somebody singing all the way through. If the value is less than 50 this indicates the that the measure is false, so for Acoustic that would be mean it probably was not acoustic.
The attributes added are:
Acoustic
Electronic
Instrumental
Tonality
Mood Aggressive
Mood Relaxed
Mood Happy
Mood Sad
We also add two special measures that are used to work out the Mood with a range of -100 to 100, these measure are called
Valance
Mood
Does the song use acoustic or non-acoustic instruments
Does the song use predominantly electronic based instruments such as synthesizers
Is the song predominantly instrumental or is there singing or talking.
A measure of the songs tunefulness
Is the mood of the song aggressive
Is the mood of the song relaxed, this in many ways the opposite of Aggressive but it calculated using a different algorithm
Is the mood of the song happy
Is the mood of the song sad, this in many ways the opposite of Happy but it calculated using a different algorithm
