Using the possessive is more natural in some cases, but it has a slightly different meaning.

1 - Bill likes Sarah singing. 2 - Bill likes Sarah's singing.

Sentence 1 means that Bill likes the fact that Sarah is singing. Perhaps she was shy, but now that she has sung in public she is less so and sings more often now. It doesn't mean that Sarah's voice is pleasant, necessarily, only that the act of her singing brings Bill pleasure.

Sentence 2 means that Bill enjoys the actual music that Sarah produces.
