メルト (Melt)

Background
This song is about a shy girl who is in love with a boy. In her pursuit of him, she gets her bangs cut and hopes he will notice, all the while encouraging herself to look cute. Her love is pure; she says that she loves him for him and not because she is in love with being in love, but it would melt her to confess. Then, it rains. She has a collapsible umbrella in her bag, which she thought was too small, but the boy joins her under the umbrella of his own will. Heart pounding, she is so happy she could cry, because in Japan sharing an umbrella is a sign of shared feelings and associated with couples. When they reach the station, she almost tells him to hold her because she does not want to leave him, and can not believe herself.

Multiple Fanmade PVs for "Melt" exist; most of them feature Miku as the protagonist, acting out the events described by the song. The "boyfriend" character is often represented by a faceless person (a technique often used to represent "Master", or the VOCALOID user), or at times by KAITO.

The song was release as ryo's first single (メルト). It was also featured on the albums supercell, VOCALOID BEST from ニコニコ動画(あか), Hatsune Miku 5th Anniversary Best ～memories～, 初音ミク‐Project DIVA‐2nd NONSTOP MIX COLLECTION, and Hatsune Miku Best ～memories～.

Popularity
"Melt" and its PVs are so popular on Niconico and YouTube that it has been featured in some Nico Nico Medleys, and has many covers and parodies both by live musicians and other VOCALOIDs.

With over nine million views, the original upload of "Melt" on Niconico is the second most viewed original VOCALOID song on the site, behind "Miku Miku ni Shite Ageru♪". It isn't quite as popular on YouTube, although one reprint of the 3M Mix of "Melt" has over five million views. This puts it far behind other VOCALOID YouTube uploads such as "Matryoshka" and "World is Mine".
