Godzilla MIDI Dataset: Over 5.8 Million Normalized MIDI Files

A collection of over 5.8 million unique and normalized MIDI files, last updated on 2025-06-06. The dataset was created by 'projectlosangeles' for Music Information Retrieval (MIR) and symbolic music AI. Each file was converted to a proper MIDI format specification and checked for integrity.

Use Cases

• Train symbolic music generation models based on the large-scale, normalized MIDI collection.
• Conduct Music Information Retrieval (MIR) research based on the deduplicated and integrity-checked files.
• Develop music analysis tools based on the extensive metadata mentioned in the description.

Strengths

• Over 5.8 million unique MIDI files.
• Files were deduplicated twice, by MD5 hashes and by pitches-patches counts.
• Each MIDI was converted to proper format specification and checked for integrity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• License information is unknown, which may restrict usage.
