The first person posts a category for the next person (e.g. "This song plays at your funeral" or "This song describes your love life"). The next person puts their iPod/iTunes/whatever on shuffle and posts what song they got for their given category, along with a category for the person after them. Wash, rinse and repeat!
Example:
