There are no compatibility problems between BIAB song files that I'm aware of. I'm still using some that I created long before 2006.

The audio track is created when the song is rendered to audio. This is a separate action and one that needs to be selected by the user. BIAB doesn't automatically save audio files from song files. There are options to "render", "save song as wav/mp3/wma" (etc.), "Save special" that will all render the BIAB backing to an audio file if the option is chosen.

If one doesn't need an audio file, then, in my opinion, it's best to stay with the default SGU or MGU file that is BIAB's native format.

Noel
