The music industry underestimated Taylor Swift

When people who work in the industry tell you how everything else has ruined their business, never forget the biggest problem is that they don't really know what they're doing.

Take how badly they misjudged Taylor Swift:

Just a couple weeks ago, industry sources were telling the music trade publication Billboard they expected Taylor Swift to sell about 750,000 copies of her new album, 1989, in its first week.

How good was that estimate?

Now, with 1989 out for just one day, Billboard says she’s likely to hit a million.

So, industry sources out by a quarter of a million copies.

To be fair to them, how could they be expected to know Taylor Swift was going to sell a million in a week? Nobody's done that since... erm, Taylor Swift did it with her last album. (Her album before that did a million, too.)

Music industry execs: they wouldn't even bother killing the goose that laid the golden egg, as they wouldn't even have realised it was laying golden eggs in the first place.
