Simple reason: It was a good movie. It's not as cerebral movie like inception or the matrix, but it was entertaining.

Yes, the reason why people can't shut up about it is largely because of the music. It had also been quite some time since Disney released a worthwhile animated movie, or a musical, and frozen was both.
