Error in source OpenScore subtitles

I found a grammar error in the source text of the OpenScore Kickstarter video's subtitles in the 4th string. Here is the original text:

"Centuries of music lies trapped between pages,⏎
waiting to be rediscovered."

"lies" should be corrected by "lie" ("Centuries lie", not "music lies").

Since I am only in the French translation team, could anyone confirm this and modify the original string? Thanks in advance.
