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".
Megurine Luka
Despite the inclusion of English, Megurine Luka was not aimed at a worldwide audience, instead focused primarily at Japanese producers. In 2010, Luka was ranked as the 3rd most popular Vocaloid product Crypton has sold. In October 2013, Luka's Vocaloid 2 software disappeared off the top 10 products charts as the Hatsune Miku V3 and its bundle package disrupted the chart rankings. Luka had already fallen to 6th place during the 2013 period as a result of the KAITO V3 release, but this was the first time Luka had disappeared from the charts. After the charts began to settle down again, Luka began to occupy the same spot on the charts that the Vocaloid 1 KAITO package previously occupied (6th-8th place), putting the popularity of the product on par with the older product. After the MEIKO V3 release, Luka became the only member of the Vocaloid 2 Character Vocal Series vocals to have a product on the charts, leaving her in 5th place. However, Vocaloid 2 vocals were mostly absent from the rankings in April 2014. By mid-2014, both she and the Vocaloid 2 Kagamine Rin\Len package no longer held constant places in the rankings and were constantly on and off Crypton Future Media sales charts. In March 2015, the Megurine Luka V4x package got the no.1 spot for the sales of all digital instruments on Big Fish Audio. Soon after the V4x package release, she grabbed the Crypton top sales rankings and remained there for April 2015. On May 1, the site updated to reveal the package now in 3rd place behind Hatsune Miku V3.
