I have been using Spotify since 2015, which at the time of writing puts me at around 9 years using Spotify. In order to comply with data privacy laws that have been enacted over the last several years, many companies have implemented ways for users to request their data. Spotify being among them, users are able to request lifetime listening history for their accounts under Privacy Settings. It takes a while for the data to be compiled, but eventually a download link is provided.
