That works fine for fixed-length tags like id3v1, but a more sophisticated
tagging format (such as musicmatch's original tagging format or even id3v2,
which can come at the end of a file) might not have a fixed length. One might
be able to use Byte-Ranges if the cost of two such calls was acceptable. For
example, all musicmatch tags end with a fixed-length field which contain the
byte offsets of the other fields. The first Byte-Range retrieves this field,
the second gets the rest.
