The short answer
Yes. Rebuilt or re-downloaded automatically when needed.
What is it?
Spotify’s PersistentCache: songs it has streamed and cached, plus music downloaded for offline listening. It often grows to several GB, more with large offline downloads.
Cached and downloaded songs. Spotify downloads them again when needed.
What happens if you delete it?
Spotify streams or caches songs again when needed. Offline downloads must be downloaded again before you can listen without a connection.
How to remove it properly
In Spotify, open Settings › Storage and click Clear cache; the same section can remove all downloads as well. Or quit Spotify and move ~/Library/Application Support/Spotify/PersistentCache to the Trash.
From the app itself: Spotify > Settings > Storage > Clear cache.
Before you delete it
Clear downloads only when you are online and do not need offline playback soon.
