a) What are the advantages of 2.4.0 over 2.3.0? All my old mp3s have 2.3.0. Any problem having some files with one type, other files with the other type?
b) Why would the ID3v2 version change due to use of the "--id3v2-only" option?
Regardless of which version of ID3v2 tag I am writing with LAME 3.93.3, the track number is being written as<track/[total tracks]>.For example, 4/10 (Track 4 of 10 tracks.)With earlier versions of LAME, I always just got the track number (without the total). That is what I prefer.
