Read MP3 metadata: title, artist, album, year, genre, track number, embedded artwork. Supports both ID3v1 and ID3v2 tags.
Reads the ID3 tags from an MP3 file and returns the metadata
as JSON: title, artist, album, album artist, year, genre,
track number, comment, composer, plus a flag indicating
whether embedded cover-art is present.
Both ID3v1 (the simpler trailer at the end of the file) and
ID3v2 (richer header at the start) are supported. When both
are present, ID3v2 wins.
Audio characteristics are also reported: duration, bitrate,
sample rate, channels, and the codec profile.
