Song Deletion Request, Privacy Questions

[tiborviszneki]

Hey Developer Community,

We built a song recommender using Spotify's API, and one of our users requested us to remove their songs from our library due to privacy concerns.
This means they wouldn't be found in the search field, and we wouldn't generate playlists with similar tracks based on their songs.

Because the songs are coming from Spotify, the reason their music is on our site is that it is also on Spotify. 

How would you approach this? I couldn't find any privacy guidelines from Spotify's documentation.

The best way to implement this, is to keep the track URIs of the songs the user don't want to see on a list in the database of your site.

Every time your site would provide a list of tracks, it should filter out the tracks on list in the database.
