If you're finding Chillout Ibiza FM to be an amazing experience, then you'll be pleased to know that there are three other channels administered by this broadcaster. All of which are designed to make life a more relaxing experience. So please check them out:

Soft Jazz UK The smoothest jazz that can be found. No really! We dare you to find a more laid back mix anywhere.
Music For Healing Designed with healers and alternative therapists in mind. But a great listen for relaxation too.
Meditation Music This one goes a little deeper. Ambient sounds to help with the process of meditation.
