なやみむようっ!! (Nayami Muyou!!)

Background
The song was first uploaded on June 1st, 2008 and is one of the tracks for the Putin-P Series. Track 6 of Part 2, it's previous song being Stealing is a Doctrine?. This song mainly talks of Rin's side to Len's "Stealing is a Doctrine?".

Rin's memories came back, and she remembered the days when she was still 'human' and not a Vocaloid. Rin remembered when she found Len (the dog), and sang about how work was hard. Later on Irina presumably died.

Japanese and Romaji Lyrics
Note: Putin-P often plays with the lyrics. In the original lyrics here, there are several emoticons; and they're not meant to be sung.

Also, another note is "0120-783-640". In Japan, there is a free phone service "0120-783-640", being related to animal care. Although it's written "0120-783-640" it's pronounced "nayami muyouu" in the song.
