Hatsune Miku
One of the Vocaloid compilations, "Exit Tunes Presents Vocalogenesis feat. Hatsune Miku", debuted at number-one on the Japanese weekly Oricon album charts dated May 31, 2010, becoming the first Vocaloid album ever to top the charts. Another album, "Supercell", by the group Supercell also features a number of songs using Vocaloids. Other albums, such as 19's Sound Factory's "First Sound Story" and Livetune's" Re:package", and "Re:Mikus" also feature Miku's voice. Other uses of Miku include the albums by Absorb and by OSTER-project. She had sung the original Nyan Cat called "Nyanyanyanyan!" by daniwell-P. Kagamine Len and Rin's songs were covered by Asami Shimoda in the album "Prism" credited to "Kagamine Rin/Len feat. Asami Shimoda". Another song original sung by Miku, "Color", was covered by Maria, and featured as the opening theme of the 2011 anime series "Freezing".
Vocaloid
The CEO of Crypton Future Media noted the lack of interest in Vocaloids overall was put down to the lack of response in the initial Vocaloid software. With regard to the development of the English version of the software specifically, many studios when approached by Crypton Future Media for recommendations towards developing the English Vocaloids had no interest in the software initially, with one particular company representative calling it a "toy". A level of failure was put on Leon and Lola for lack of sales in the United States, putting the blame on their British accents. Crypton praised the value of the English Vocaloids and what they offered to the Japanese users for their capability of offering the English language to them, when it would otherwise be off limits. As Hatsune Miku was responsible for making the software famous, her voice has become the most commonly associated with the Vocaloid software and divides opinions of critics both overseas and within Japan on their opinions towards her and the software. Crypton blamed a fear of robots on part of the lack of response on the sale of the software overseas and expressed that there was also a general "anti-Vocaloid" point of view amongst some cultures and communities, although he also noted that he hoped in the future this would change as the software continued to be developed. Prior to the release of the Hatsune Miku product, Crypton Future Media had also noted there was some criticism at choosing to release the original Vocaloid engine as a commercial licensing product, although felt that the choice was for the better of the engine. Furthermore, it was noted that the original Vocaloid engine felt more like a prototype for future engine versions.
