Feature description:
During media provider scanning i’ve noticed that will not import flac with embedded cue sheet but only wich have external one.
Problem solved:
Flac have two metadata block where saving cuesheet file.
A version that only contains structural info to take the cue points information are saved in CUESHEET METADATA block (this feature are used for have a real backup copy can reproduce original physical structure of original source)
The second mode to embed cuesheet in FLAC are made storing information in VORBIS_COMMENT METADATA block with the others tags. This method are used and supported for example by Foobar2000 and Kodi. Of course made necessary manage multi track information using a prefix of tag that are associated at track level: cue_track>>n.<<_>>tag name<<.
Following an example of a bit verbose VORBIS_COMMENT METADATA block of a my album with embedded cuesheet.

All this to presume that if have made a parser for cuesheet files, cuesheet’s tag contains the same information.
Brought benefits:
Manages libriaries with per-track files and per-album file that have external cuesheet informations jointly does bit complex. I have studied deep the way to embed cuesheet in file flac. Through this way I have finally forget all chuesheet’s limits chained at old concept of local charsets. Vorbis comment are full utf-8 compliant. utf-8 contains chars of worldwide!!
My personal experience tell me that have a per-album file with cuesheet embedded jointly per-track file make better manage of my music files… so natural!
Other application solutions:
Kodi, Foobar2000
