For those who want to fall asleep quickly, try some relaxation techniques and music to help you fall asleep. The sleep songs I recommend are as follows:

1. "Lullaby": This is a very classic lullaby.

2. "Mountains and Flowing Waters": This is a very natural piece of music.

3. "Sound of Rain": The sound of rain is a very natural sound effect.

4. "Meditation Song": This is a piece of music specially designed for meditation and relaxation.
