Generic content is music that our partner terms determine have non-distinct artist names or track/project titles. This could be an album called "Ocean Noise", a track titled "Rain Sounds' or an artist who goes under the name Yoga Music.
iTunes partiulcalry have very strict policy around what they consider to be generic names and titles and will reject any release they deem 'generic'. The iTunes guidelines states:
2.10. Generic Artist Names. Generic artists, such as Yoga, Workout, Meditation, Baby, Christmas, Top Hits, Chorus, Orchestra, or Singer are not accepted in any genre. Cast names must be specific to a given show or production. When you don’t have a specific artist name or are working with studio musicians, list the production house, label name, or studio as the artist name.’
If you think your release might fall into this category then we recommend you make your release and artist information more specific by having customised track titles, thinking of a distinctive album/EP title and ensuring your artist name is unique. To understand why you need a unique artist name, read this blog post.
