The common "problem" that Bing and Google could both potentially be upset with RapGenius is the there is no accountability to the site owners. The search engine's job is to serve results that people want to see. In general, you can absolutely count on them to make decisions that they think will benefit their total relevance in aggregate, even if it hurts a particular subset of queries.

But that's not really so much of a product problem as a problem with the problem itself. In other words, it's not really clear that a better product will fix that, because the incentives will probably always point to doing this rather than not.
