使用Spotify API搭建音乐网站：可存曲目数据及合规性咨询

Hey there! Let's break this down clearly since I've navigated Spotify's developer terms while building similar music-focused tools.

Is Storing Spotify Track Data in Your Own Database Allowed? #

First off, yes, this is allowed—with key caveats laid out in Spotify's Developer Terms of Service. The core rule here is that you can store non-real-time, non-personally identifiable track metadata, but only to support the functionality of your app that uses the Spotify API.

Some critical restrictions to keep in mind:

• You can't store any copyrighted content (like audio files, full lyrics, or album art files—you must link directly to Spotify's hosted art URLs instead of downloading and hosting them yourself)
• Stored data can't be sold, licensed, or used for any purpose unrelated to your app's integration with Spotify
• You need to periodically sync your database with the Spotify API to ensure metadata stays up-to-date (e.g., if an artist changes their name or a track's popularity updates)
• Never store any user-specific personal data unless you have explicit user consent (though this doesn't apply to general track metadata like artist names or popularity)

What Track Metadata Can You Safely Store? #

Spotify allows storing most of the standard track metadata you'd need for custom filtering and sorting. Here's a list of common, permitted fields:

• Track core details: Name (name), unique Spotify track ID (id), popularity score (popularity), duration (duration_ms), explicit content flag (explicit)
• Artist information: Artist name(s), artist ID(s), artist genres (artists.name, artists.id, artists.genres)
• Album details: Album name, album ID, release date (album.name, album.id, album.release_date)
• Additional identifiers: ISRC code (external_ids.isrc)

Just make sure every piece of stored metadata is tied to its corresponding Spotify ID—this makes it easy to refresh data later and ensures you're adhering to attribution requirements.

Quick Final Note #

As long as you stick to these guidelines, building your own database of Spotify track metadata to enable advanced filtering/sorting (like genre combinations, custom popularity ranges, or album release date sorting that the API doesn't support natively) is totally valid and compliant.
