The first difficulty-bucketed word-level lyrics alignment benchmark for
sung vocals.
Existing lyrics-alignment evaluation reports one blended number. Singing
fails aligners in different ways — fast rap, melisma, held notes, vocals
buried in the mix — and a single number hides all of it. This benchmark
tags every track with its dominant difficulty and reports metrics per
bucket.
