Sonic access/sonic access 4 seasons has a meditation track, music track, and a song.

Will I need to follow the 20 minute rule?

For example, can I listen to a Sonic access track then immediately listen to a paraliminal or would it be better to do sonic access, 20m break then a paraliminal?

Also I think the music track of sonic access doesn't have Holosync??? If I listen to track 1 meditation, track 2 music..... Would the music track count as the 20-30 minute break before a paraliminal?
