When using `--limit N`, only the first N songs are scanned against channels, significantly reducing processing time for large songlists. +- **Fixed --limit logging accuracy**: The logging messages now accurately reflect the number of songs that will actually be processed when using `--limit`, rather than showing counts for all songs in the songlist. +- **Resolved import conflicts**: Fixed inconsistencies between different `extract_artist_title` implementations across modules. + +### โœจ Enhancements +- **Enhanced fuzzy matching**: Improved `extract_artist_title` function in `fuzzy_matcher.py` to handle multiple video title formats: + -
