I am trying to add a custom song field to the WP built-in post, so that we can attach a song from a previously filled database to every post (in an attempt to popularize our music through posts).
I can display a custom field group at the WP default post type, but I don't want to manually add the songs to every post, filling out the cover image, song title, album title, etc... Instead I want to be able to pick the song from a list when I write the post. But there is no option to add such list to a custom field group... or is there?
Please help me solve this, it would be really awesome if we could make it work without excess manual labor. Thanks.
