Store CUE data in metadata

[LyricsLover]

Small addition:
If you use FLAC files, you could use
metaflac.exe --import-cuesheet-from=album.cue album.flac
this would embed your information as a special CUESHEET block.

Compatibility with players may vary.

Working with CUESHEET blocks in FLAC files - detect and remove

Yes — metaflac or foobar2000 is the way to go here. The cuesheet is not part of the actual FLAC tag (which is Vorbis Comments or METADATA_BLOCK_VORBIS_COMMENT), but resides in a different block type called METADATA_BLOCK_CUESHEET. That's also the reason why it's not visible in extended tags. I've added it to my list of future ideas for improvement.
