The aligner had to explain every frame of a section with the lyrics, so
background speech or laughter between lines pulled the next line's
letters onto it, which then came out as a burst of tiny notes before the
real line was rushed to catch up. MMS_FA has a star token that matches
any audio; put one before, between and after the lines of each section,
as ctc-forced-aligner does by default, and drop the stars' spans from the
result.
