I tried it last night and for the first time in about 4 months I succeeded!
The relaxation music you posted worked like a charm and I totally forgot about my body because it was so hypnotizing and suddenly I felt a wave of energy flowing through my body and it got so heavy. At first I was a bit shocked because this never happened before but then the wave came again and my body felt like I was pinned down.
The bad thing was: I couldn't finish because my cat came inside my room and jumped on my stomach
Nevertheless: THANK YOU!
