The align, transcribe, lyrics and notes tests quoted lines from published songs, and the UltraStar parser fixtures were complete community charts of commercial songs. Replace them with counting words and two hand-written charts that keep what the parser tests rely on: CRLF line endings, Latin-1 bytes, a decimal-comma BPM, freestyle/golden/rap notes, negative pitch and a two-number line break.
