You know those special editions of different albums? There's "limited first edition" version, certain countries get certain songs while others don't, you can get some tracks only online, there are tour editions of some albums, what? When I buy an album I would like to have everything that particular album is supposed to have. I don't want to search the internet for knowledge which songs I'm missing from an album that I have bought with money. Recently this has annoyed me with 'Fiction' and 'We Are The Void'. Apparently there are some songs which have existed for years and I've only found about them recently.
