What kinds of tags does FLAC support?

FLAC has it's own native tagging system which is identical to that of
Vorbis. They are called alternately "FLAC tags" and "Vorbis comments".
It is the only tagging system required and guaranteed to be supported by
FLAC implementations.

Out of convenience, the reference decoder knows how to skip ID3 tags so
that they don't interfere with decoding. But you should not expect any
tags beside FLAC tags to be supported in applications; some
implementations may not even be able to decode a FLAC file with ID3
