I need help "linking" one post type to another.
I've got one post type called 'album'. This contains the title of the album and the track titles entered into a text field with unique names (track1, track2, ...).
Then I've got another post type 'lyrics' with more information about each song (text, file attachments, creator information, ...).
Inside 'lyrics' I need to be able to select which track I want to add information about.
How can I do that?
