Every track/bundle must have a main performing artist that will be marked as 'primary' in all shops. If there are two or more primary artists performing, create a new 'interpreter' that will include all primary artists (e.g. Artist 1 & Artist 2).

For certain kinds of cooperation, special roles such as „versus“, „feat.“, „meets“, „with“ are necessary. If you want that your interpreters will be listed with these roles in shops, you have to create their role correctly, for example: „Madonna feat. Lady Gaga“ or „Jay-Z vs. Usher“.

You also have to add composers, authors and publishers. These contributors won't be shown or will only be partially shown.
