Well, first off, I do not include any samples from their MP3s, nor do I include reproductions of their copyrighted sheet music. Second, I am careful to link out to the artist's content on iTunes and YouTube. So hopefully the music industry understands that I am driving users to their songs. If a user wants to listen to Justin Bieber's Baby, they won't be able to do so within my app. They'll need to go download it from iTunes, or be the 756 millionth viewer on YouTube. But honestly, I'm not trying to infringe on anyone's content. I just want to make a fun app to drive up interest for various artists and songs (not that Bieber needs my help). But if they contact me and want a particular song removed, I will be happy to do so.
