Why aren't PERFORMER/TITLE/etc tags stored in the FLAC CUESHEET block?
This has turned out to be a pretty polarizing issue and requires a long explanation.
The original purpose of a cue sheet in CD authoring software was to lay out the disc, essentially specifying how the audio will be organized on the disc; some of the information ends up as the CD table of contents: the track numbers and locations, and the index points. Later CD-TEXT was added. But CD-TEXT is a very complex spec, and actually goes in the CD subcode data. It is internationalized, not through Unicode, but with several different character sets, some of them multi-byte. It even allows for graphics. In cue sheets, the TITLE/PERFORMER/etc tags are just a limited shorthand for authoring CD-TEXT, but when you rip, you almost never parse the CD-TEXT, you get it from another database, and it doesn't really belong in the FLAC CUESHEET block.
For FLAC the intention is that applications can calculate the CDDB or CDindex ID from the CUESHEET block and look it up in an online or local database just like CD rippers and players do. But if you really want it in the file itself, the track metadata should be stored separate from the CUESHEET, and already can be because of FLAC's metadata system. There just isn't a method specified yet because as soon as it is, people will say that it's not flexible enough. From experience (and you can see this come up time and time again in many lists), anyone who is going to the trouble of keeping a lossless collection in the first place will already be picky about metadata, and it is hard to come up with a standard that will please even the majority. That is the big problem with metadata and is why Xiph has deferred on it, waiting for someone to come up with a good metadata spec that can be multiplexed together with data.
Some players (for example Foobar2000) allow you to store the CDDB data as FLAC tags and can parse that.

FLAC对于Cuesheet的标准是有些问题的。现在我为了方便WAV一律转WavPack，软件支持广，内置cuesheet也没啥问题。
APE这种切track都要卡的破烂有多远滚多远。
