Frequently Asked Questions

Moonstone is a beautiful Spotify playlist analytics tool that helps you discover insights about your music taste. Unlike standard music apps, Moonstone reveals patterns in your playlists with visual activity charts, interactive heatmaps, artist repetition analysis, and decade distributions. It's designed for playlist creators and music enthusiasts who want to understand their collections on a deeper level.

Absolutely! Moonstone prioritizes your privacy by not storing any of your Spotify data in a database. We only access your data temporarily through Spotify's official API during your session, and all processing happens within your browser. Your playlist information, liked songs, and listening history are never stored on our servers, making Moonstone one of the most privacy-focused Spotify analytics tools available.

Moonstone reveals fascinating insights about your playlists including when songs were added (with monthly activity charts and calendar heatmaps), which artists appear most frequently, distribution of music across decades, genre breakdowns, and popularity scores. For profile galleries, you'll discover patterns across all your playlists with timeline visualizations and comprehensive statistics about your music curation history.

No! Moonstone works perfectly with both free and Premium Spotify accounts. All of our analytics features are available to all Spotify users regardless of subscription type. You can analyze public playlists even without logging in, while features like Liked Songs analysis require authorization with your Spotify account.

Simply log in with your Spotify account and navigate to the 'Liked Songs' section. Moonstone will generate comprehensive analytics including top artists, genre distributions, decade breakdowns, and popularity analysis. You can also browse your full collection with filtering and search capabilities – all while being able to play your songs directly within Moonstone.

Profile Gallery is one of Moonstone's most powerful features that analyzes any Spotify user's public playlists to create a comprehensive overview of their music curation. It shows aggregated statistics, an interactive timeline visualization of when playlists were created and updated, and provides enhanced playlist cards with much more context than Spotify's standard view – including active months ratio, top artists, and genres.

To ensure fast, reliable performance, Moonstone currently analyzes up to 1,000 tracks per playlist, 2,000 tracks for Liked Songs, and 1,500 tracks across multiple playlists in Profile Gallery views. When these limits are reached, you'll still get valuable insights based on the analyzed tracks with a clear indication of the percentage analyzed.

Yes! Moonstone is currently free to use during our beta testing period. We're focused on creating the best possible playlist analytics experience for music lovers. While we may introduce optional premium features in the future to support development, we're committed to maintaining a powerful free tier.
