What styles of meditation help with Astral Projection?

So I recently read this post which emphasized learning deeper meditation (to the point of your senses shutting down) as a necessary prerequisite to Astral Project from fully conscious. What sort of meditation practices and what specific traditions can help with learning that?

Also - in my previous attempts I have listened to meditation music while waiting to AP - is this counterproductive to said aim of shutting senses down because it actively engages your listening?

Thank you
