In their apology, Aniplex has invited any customers with faulty CDs to send in their name, address, phone number and disc to them so that they may be replaced with corrected soundtracks and the faulty discs can be thrown out.
Yuki Kajiura, the composer of the soundtrack, has since released a series of tweets addressing the mistakes, regretting that it has taken this long for staff to notice them.
今までこのCDをお楽しみ頂いていた方には、ほとんどの曲を異なったピッチで聞いて頂いていた事になります。自分で気付かなかったのが何よりいけないんですが、私にもかなりの衝撃でした。本当に申し訳ありません……。

In one tweet, she stated: "To those that have been enjoying the CD until now, I've only just heard all of the mistakes in the songs. I simply can't believe I didn't notice until just now. I truly feel terrible about this."
