The "Moment Ring" CD single by Love Live! School idol project idol unit μ's sold 96,479 copies in its first week, and it ranked #2 in the Oricon singles chart for the week of February 29-March 6. The single, which shipped on March 2, has the highest first-week sales in the franchise's history. It outsold the previous record holder, "Boku-tachi wa Hitotsu no Hikari"/"Future Style," which shipped 96,150 copies last July with songs from the Love Live! The School Idol Movie anime film.

The new single also tied the franchise record for the highest ranking in a single's first week. The #1 single this past week, "Unlock" by the male idol group Kat-tun, sold about 195,000 copies.

"Moment Ring" ranked #2 on the daily Oricon singles charts with 35,099 CDs sold on March 1. The single ranked above new single "Yell" by male group Chō Tokyū (Bullet Train), which sold 18,886 copies. However, "Moment Ring" was outsold by "UNLOCK," which sold 116,130 copies.

The "Moment Ring" single is being marketed as the group's "final single." The single contains the single's title song, as well as the song "Sayōnara e Sayonara," and instrumental versions of both songs.

The group will hold the "μ's Final Love Live!" concerts at the Tokyo Dome on March 31-April 1.

Although the voice actress' contracts will expire at the end of March, and the March 31-April 1 concerts are billed as "μ's Final Love Live!," μ's group member Emi Nitta stated that the concerts will only be the final concerts with just μ's as a whole and by themselves (without other musical acts), and does not characterize this as the group's "breakup." Group member Sora Tokui added that the "μ's Final Love Live!" concerts are planned as a culmination of their work.

The μ's idol group was the eighth best-selling musical act in Japan in 2015.

The group last performed in the Kōhaku Uta Gassen, the New Year's Eve singing contest that is Japan's most viewed music television program, although Eli Ayase voice actress Yoshino Nanjou did not perform in the event.
