  WikiMT++ is an expanded and refined version of WikiMusicText (WikiMT),
featuring 1010 curated lead sheets in ABC notation. To expand application
scenarios of WikiMT, we add both objective (album, lyrics, video) and
subjective emotion (12 emotion adjectives) and emo\_4q (Russell 4Q) attributes,
enhancing its usability for music information retrieval, conditional music
generation, automatic composition, and emotion classification, etc.
Additionally, CLaMP is implemented to correct the attributes inherited from
WikiMT to reduce errors introduced during original data collection and enhance
the accuracy and completeness of our dataset.
