Here's what I mean: I have several songs stored as individual mp3 files. I have amalgamated them into one large mp3 file. When I play the file with VLC or any other piece of audio player software, the entire file just plays from start to finish as expected. If I press the "next track" button, the right facing arrow next to a vertical line, the player software just starts the entire file from the beginning again. What I want to do is put some kind of marker in between the individual tracks so that after I amalgamate them into one big audio file the audio player software will interpret pressing the "next track" button to mean "jump to the next track". Essentially, what I want to do is somehow "trick" the audio player software into interpreting my single audio file comprised of amalgamated files as a CD with the typical "next track" button interface. How can I do this? I'm not committed to the MP3 format. If I can get this to work with another format, that's fine as long as that format is common enough to be played by the major pieces of audio file player software e.g. VLC, Windows player, etc. Thanks.
