It looks like you’re asking for a report on a specific file or release:

| Aspect | Notes | |--------|-------| | | Usually 16-bit / 44.1 kHz (CD quality) | | Authenticity risk | Transcodes from MP3 to FLAC are common in unofficial releases | | Spectrum check | A true FLAC shows frequency content up to 22.05 kHz (no sharp cutoffs) | | Source | Likely ripped from CD singles/albums, not a unified greatest hits master |

If you want, I can help you (e.g., commands to run on Windows/Mac/Linux) or suggest the official compilations available in high-res audio. Just let me know.
