One of the features that set Spotify Top is that you can easily share your music stats. Other people can see them just by following a link. Your list of top artists, songs, and genres are updated daily. No need to take screenshots nor code any complicate integration with Spotify.
Your report also shows a useful image showing the image of your 3 most listened artists during the last month. This makes it a great way to preview the report and looks great on sites like Twitter or Facebook.
Last, but not least, other Spotify Top users can discover your profile browsing through content like genres.
