If you hit just "Play" and haven't made any changes to the song since you last hit "Play", it will play exactly the same thing as the previous time you hit play.

If you make certain changes to the song and hit Play (for example, if you changed a chord), it will regenerate the song (meaning there will be subtle, and sometimes not so subtle, changes to the song from the last time you hit play). Not every change results in a regeneration. For example, if you add some MIDI notes to the Melody track, it won't regenerate the style tracks, but just play the new melody over the existing generated version of the song.

If you hit "Generate and Play", it will explicitly regenerate the tracks for the song (except for any that are frozen) and then play (and will sound slightly different from the previous time.

That's how BIAB works. You don't get the exact same arrangement each time.

Hope that helps.
