As the title suggests, I have listened to lots of the ASMR videos on YouTube, and although they are extremely relaxing and soothing, I do not think they are what I want to use in my piece. I think the idea I have previously stated is more in keeping with what I want.
Do however try and listen to the ASMR tracks yourself and I will stand by the fact that they are the best solution to a sleepless night I have ever come across. I also found that sitting in the dark with your eyes closed listening to it can make stress levels dramatically fall.
