I have used this CD many a time to send myself to sleep after a stressful day. The music is very calming and euphoric but the HUGE, MASSIVE noise of crashing waves and the violent tide can kind of keep you wide awake and alert. I reckon that Solitudes should have lowered the volume on the waves a bit. Whether through speakers or headphones, the tide will always come through loud. If you can ignore this, you'll crash out.
