Do you remember Pandora? For those of you that don’t, Pandora was a fairly popular music service about 10-15 years ago that worked like a curated radio station. You could seed a playlist with songs or an artist, and Pandora would try to pick songs with similar tags to play for you. You could thumbs up and thumbs down songs. If you gave it a thumbs up, then that song would be added to the station you created and would influence future songs. If you gave a thumbs down, that song wouldn’t play again and it’s tags would be less featured in the future.
