I bought the CD because of the many positive reviews and can not understand that they should act "relaxing" really. I've given up totally annoyed after about 15 minutes. The drum alone (with sporadic quiet background noise) would have been relaxing, but - about 1 minutes after the Preview a loud, dominant noise comes about that the quick rattle on an old typewriter resembles (or permanent operation of a staple gun), then comes yet a sound means that sounds as if someone beats with fast rhythm with a stick against a Coke can that is then permanently so on and on and on. The pleasant, rhythmic drum is thereby totally under, you get the feeling you are in a busy office and really just want to "SILENCE !!!" scream. After about 15 minutes I no longer endure and abandoned the permanent clatter. Since my friends the CD also did not like it landed in the yellow bag. Pity about's money.
