Are lyrics not a PLUS feature now?

I mysteriously am able to put lyrics into tabs, without a PLUS subscription. Is this a new update?

This is most likely an error - we recently added lyric support for our Hooktheory Classroom suite for K-12 schools and may have inadvertently turned it on for non-Plus members. Thank you for pointing it out.

@bigyihsuan, actually, I forgot, the lyrics feature works up to 40 or so characters without a Plus membership. Likewise, you can use two magic chords or loop twice without a Plus membership. It is how we let people try the Plus features.
