As Oliver as my most fave vocaloid I may have many oliver song suggestion(oliver sings a lot of depressing and scary songs)

Fear Garden-Rin
Ephesus- Oliver
Secrets of Wysteria- Oliver
Tarantula- Oliver
Bacteria Contamination- Miku
Kagome kagome- miku and luka
Twaddles of a flue faker- Oliver

Most of Oliver's song is scary but if you are not interested in english vocaloids then his songs is not your type
