Currently just builds a dataset given a list of user ids.
To get your user id, just visit your Spotify profile:
Click on the (...) icon -> Share -> Copy Profile Link/URI.
The user id is the part after the last "/" or ":"
Might spin this up into a web app later.
I'm using lyrics.wikia's API to get lyrics info, might switch to Musixmatch later.
I own none of the data fetched using the API, and do so only for academic purposes. Peace.
