Im also wondering if there is something about the music that you are playing that is triggering (upsetting/uncomfortable for you or too emotionally filled otherwise for you to handle) my reason for wondering this is people dont mentally run away (dissociate) from things /feelings/emotions that they are ok with and can handle doing/feeling.

example one song repeatedly caused me to dissociate to the point of switching into an alter. upon further investigating this with my treatment provider it was discovered a favorite relative of mine who had died used to play that song. my mind would dissociate when ever this song came on the radio or I played it because I was feeling all kinds of heavy/hard to handle emotions/memories of that favorite relative. once we discovered this, this song no longer caused me to dissociate/switch into that alter.

maybe even though you are purposely playing this song with the express purpose of causing yourself to dissociate (feel numb, space out switch into an alter) maybe unconsciously you are triggering a painful memory/painful emotion /painful event that your mind has dissociated from your awareness because you could not handle it. if this is the case you may end up doing more harm then good. I know some people who purposely caused their self to remember things/trigger dissociating and the result was devistating. some some hosts and alters ended up suicidal, psychotic, those alters who's job, purpose reason for being was to protect the secrets and make sure the "do not tell" rule was followed ended up trying to kill /punish the host and alters that were triggering /trying to force things to go faster then they (the host and internal system could handle)

my suggestion talk with your treatment providers, let them know you are purposely triggering yourself to have your dissociative problems/symptoms (yes switching into alters is considered a dissociative problem/symptom in mental health terms).

they can help you to work on things in a safe environment and with emergency plans in place so that if you and your treatment providers decide to continue to purposely cause you to have more dissociative symptoms/problems like purposely dissociating/switching into alters...

this way too you and your treatment providers can discuss the possible legal /ethical ramifications in your location that you may be accidentally putting your treatment providers in by not informing them that you are doing this example here in NY is illegal and unethical for treatment providers to do this knowingly and unknowingly, due to risk factors and false memory syndrome and therapist induced psychosis/mental disorders. here when treatment providers find out their clients are purposely causing their mental disorders to escalate (have more symptoms) they have to take a break (in case the issue is one of where clients are doing it to please their treatment provider rather than get healthy) and then work on stability. Sometimes a 72 hour hold/evaluation is done to make sure the client doesnt have any self harm/suicidal/homicidal reactions residual affects from this from the host or alters.
