landed on the doormats of songwriters

作曲家がYoutubeなどからもらうロイヤリティが低いなんて知りませんでした。赤字で示したland on the doormatですが、こちらはう郵便でドアの下に明細書が届いた段階にすぎないことを、面白おかしく書いています。(Othello)

There's been much speculation as to the enormous amount of money Psy must have raked in from the hundreds of millions of hits his Gangnam Style video has had on YouTube. There's no way of knowing for sure, as all Google/YouTube deals are covered by non-disclosure agreements – and do not allow independent labels to demand audits. However, the chances are that though the amount won't be insignificant, it will be much lower than one might think. And, judging by the royalty statements that just landed on the doormats of songwriters all around the world, we can be certain that the co-writer of the track didn't earn a fortune off YouTube
