The only way I can think that music would affect the heart beat! is by increasing the amount of the hormone adrenalin secreted by the pituitary gland. Andrenalin control the pacemaker cells of the heart and regulates the heart beat. So if there is more adrenalin, the heart beat would go faster. The same would occur with Coffee/Caffeine.

Normally this would not occur. Beats between regularly spaced beats are called premature contractions and can occur with either the top or bottom chambers of the heart. This has the potential for causing an irregular heartbeat called an arrhythmia.
