In the Irish Independent, a writer recounts his personal experience, plus a meta-analysis, on how insomnia may be treated with music therapy.

In all countries the pieces were “characterized by a tempo of 60-80 beats per minute, slow, stable rhythm, low-frequency tones, and soothing and relaxing melodies,” according to the authors. So gentle waltzes, the prayerful and restful polyphony of Thomas Tallis or the delightful music of Bach would all suffice. Tender folk rhythms such as The Sally Gardens or The Spinning Wheel might also work.
