Attractive Museum is OSTER project's 9th album. It contains 14 tracks, sung by Hatsune Miku, Kagamine Rin, Kagamine Len, Megurine Luka, KAITO, and MEIKO. The album is rounded off with a VOCALOID musical reminiscent of how OSTER project's 4th album (Cinnamon Philosophy) also ended with a VOCALOID musical. This time around, the musical is based off of The Wizard of Oz and is thus titled, The Music Wizard of OZ.
A crossfade of the album can be heard on Nico Nico Douga.
