## Why it matters

Twitter Card tags enable richer previews when sharing links on X. They support various formats such as Summary Card, Summary with Large Image, and Player Card for video content.

## In practice

Spotify uses the Twitter Player Card for sharing songs, so users can preview music directly on X. Without Twitter Card tags, only a plain link without a preview image would be displayed.
