Earlier this year, Pandora announced its plans to challenge Spotify by taking aim at one of its rival’s top features: personalized playlists. Pandora in March began rolling out dozens of variations of personalized playlists, including those spanning moods, activities, and genres – all powered by its music database, the Music Genome. Today, Pandora says the rollout has completed and all its Premium users will now have access to these new playlists.

The feature is meant to offer Pandora’s free users a reason to upgrade to its top-tier paid offering, Pandora Premium. This $9.99 per month service offers on-demand listening, playlist creation, downloads for offline listening, unlimited skips and replays, higher-quality audio and no advertisements.
