InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
This dataset seems worth looking into: https://github.com/mdeff/fma. I think you'll have a hard time identifying subgenres since even people don't know what subgenre a song belongs to. It's a very subjective classification compared to distinguishing between main genres; e.g. rock, rap, and country. Also, from my work with the Spotify API, there a lot of seemingly synonymous subgenres which will make this task even more tedious (what is the difference between "pop dance" and "dance pop"?).
NOTE:
The number of mentions on this list indicates mentions on common posts plus user suggested alternatives.
Hence, a higher number means a more popular project.
