At first I thought it would be some kind of DSBM, of course, because it's understandable, depression, darkness, and all that,
But I decided for myself that death is freedom and there can't be anything gloomy in it, all the bad things that led me to want to die are all part of life itself, all the pain I feel is part of life. Death is not life, so death has nothing to do with any of that.
So, I would spend my last hours completely abstracted from all the bad things, knowing that in what's about to happen to me, none of it will happen, I would abstract myself from everything, listening to hard breakcore, with its inhuman 200BPM drums, alternating with light ethereal, almost childlike melodies
