Here is an interview that questions whether there is gay artists in the music industry and more specifically the 'rap game' as the interviewed calls it. But can be considered as controversial is that he states that there is a 'gay mafia' and that they are controlling the hip hop scene. For instance he refers to Lady Gaga and how she is running with the gay community and she is winning!
Apple recently released a radio program similar to that of Pandora, another online radio service. While Pandora uses mathematical algorithms to choose music for the listener, iTunes Radio will use humans/Apple geniuses to choose music similar to tracks the listener likes. Katy Perry is featured as the guest DJ currently, where she shares an insight to her musical taste and artists that inspire her. She inserts her commentary and shares an anecdote occasionally. I found this interesting because a good portion of the music she chooses to play are rap songs or songs with a darker undertone, not what most people would expect perhaps?
