Single releases don't become part of the album on iTunes music purchases

This is stupid. I purchased the singles before the album came out.

So why are they not part of the album? When I went to purchase the album, it said, "Complete my album". So really it didn't mean that, it meant, get the other songs you don't have. This needs to stop, this is the digital age, we aren't getting the vinyl records when we purchase, early release songs should always end up grouped into the album after the customer "completes my album".

I will never buy another single.
