They started out with rap, but have expanded their technology to many other sites, including more general lyrics and news. Starting out in rap made a lot of sense. Rap has more lyrics than most other genres and also includes a more unique vernacular than other genres. Whereas many rock lyrics are purposefully vague and open to interpretation, rap tends to be more literal and straight-forward, but also requires some familiarity to understand its lyrics. A lot of this stuff can be easily explained with annotations.
