	'''ID3v2''' is a tagging format for MP3 files, designed to provide a much greater deal of functionality and flexibility over its predecessor, [[ID3v1]]. ID3v2 allows for a much greater amount of metadata to be embedded within MP3 files over [[ID3v1]], allowing each frame (metadata field) to contain practically any conceivable type of information, including title, album, performer, lyrics, equalizer presets, album art and other images, and much, much more.

	One of the design goals of ID3v2 was flexibility and extensibility.

	ID3v2-tagged files are also generally safe to be played on players that weren't designed to support them. They are sync-safe, allowing MPEG audio decoders to determine the tags contain no audio data and can be safely skipped.

	Even though ID3v2 is designed to support a lot of space-heavy features, such as inline pictures and file inclusion, ironically, ID3v2 still tries to use bytes as efficiently as possible, and allows for compression of each frame. If you convert an [[ID3v1]] tag to an ID3v2 tag, it is likely that the ID3v2 tag will be smaller. If you convert an [[ID3v1]] tag with full fields (that is, all 30 bytes are used in every field) to an ID3v2 tag, it will be 56 bytes larger. Note that this is the worst case scenario with regards to tag size for [[ID3v1]] to ID3v2 conversion.

New page

ID3v2 is a new tagging system that lets you put enriching and relevant information about your audio files within them. In more down to earth terms, ID3v2 is a chunk of data prepended to the binary audio data. Each ID3v2 tag holds one or more smaller chunks of information, called frames. These frames can contain any kind of information and data you could think of such as title, album, performer, website, lyrics, equalizer presets, pictures etc.

<center>[[Image:id3v2_blocks.png|frame|center|Example ID3v2 Tag]]</center>

One of the design goals were that the ID3v2 should be very flexible and expandable. It is very easy to add new functions to the ID3v2 tag, because, just like in HTML, all parsers will ignore any information they don't recognize. Since each frame can be 16MB and the entire tag can be 256MB you'll probably never again be in the same situation as when you tried to write a useful comment in the old ID3 being limited to 30 characters.

Speaking of characters, the ID3v2 supports Unicode so even if you use the Bopomofo character set you'll be able to write in your native language. You can also include in which language you're writing so that one file might contain e.g. the same lyrics but in different languages.

Even though the tag supports a lot of byte consuming capabilities like inline pictures and even the possibility to include any other file, ID3v2 still tries to use the bytes as efficient as possibly. If you convert an [[ID3v1]] tag to an ID3v2 tag it is even likely that the new tag will be smaller. If you convert an [[ID3v1]] tag where all fields are full (that is, all 30 characters are used in every field) to an ID3v2 tag it will be 56 bytes bigger. This is the worst case scenario for [[ID3v1]] to ID3v2 conversion.

Since it's so easy to implement new functionality into ID3v2, one can hope that we'll see a lot of creative uses for ID3v2 in the future. E.g. there is a built-in system for rating the music and counting how often you listen to a file, just to mention some brainstorm results that are included. This feature can be used to build playlists that play your favourite songs more often than others.
