Why do the lyrics for songs disappear or become inaccessible?

[#1]

Played songs that had lyrics.
While later lyrics don't appear for those songs.
example: https://open.spotify.com/track/37F7E7BKEw2E4O2L7u0IEp?si=51dc1262d19c41d9
song used to have lyrics but now the song appears to not.

Hey there!

Spotify is partnered with a service called Musixmatch, which provides time-synced lyrics to Spotify, Apple Music, and other companies. Sometimes due to licensing agreements, they're not able to show some lyrics on their platform. I'm no legal expert, so this is all the information I can give you.

Currently, Limbo on Musixmatch gives me a restricted lyrics error.
