Lame Info tag contains information about number of MPEG frames in file, as well as about total number of bytes.
It looks like LAME stores file size as the latter value, but I think it would be better to store stream size, because various tags can be added or removed later.
By the way, foobar2000 (when using "fix header" command) stores exactly stream size.
Are there any official specifications clearing this issue?
