Because some sounds on albums are silence containing no music but are sold as songs.

So i guess Apple should instead individually label the one track silence as neither clean or explicit? Ah genius, it's label is based on the album's language as a whole, not as a individual track. But of course, since he works for M$ I can't expect much in the way of insightful and detailed investigative reporting involving anything Apple.
Even more humorously, three of the tracks -- all titled "Silent" and all by hip-hop group Slum Village -- are labeled as explicit, even though there is only silence. For those who worry that the lack of sound will be too racy, iTunes offers "clean versions" as well.
