Well, I think its preference, but those songs are pretty good. If you like +Danshi then you might like No Title or Kurumi Ponchio, the latter has innuendo but I think No Title is pretty normal a song.

For more of the same stuff you could also listen to 2-faced lovers and Straight-faced science girl but for something happier then try Death should not have taken thee or Maid Factor.

Thanks for the suggestions I love vocaloid and have alot of both Reol and Wowaka's tracks on repeat, Hibikase and Two Faced Lovers are my faves, havent heard Straight faced scinece girl or Maid Factor though....I just noticed alot of really catchy songs tend to be dirty or sad...but not all of them

I personally Reccomend Odds and Ends from Ryo (I think its the same person that did world is mine) and Black Gold....its a Luka Song but I forgot the producers name...

There's definitely a trend for good songs being pretty sad, but there's also a lot of funny or nonsensical ones. Normal ones too, like Tengaku. Add that to the recommendation list and I'll pile on even more!

I think you're right on Ryo being the writer for World Is Mine. You could also try Neru's songs.

Abstract Nonsense
Lost One's Weeping
World's End Dancehall
the Evillous Chronicle Songs
Feather's Across the Seasons
6 Trillion Years and Overnight Story
Sun Quan the Emperor
Romeo & Cinderella

I love Neru! and Pinnochio as well!....I also have a fondness for denpa songs like Denparadigm

Kurumi Ponchio and Straight-Faced Science Girl are very innuendo laced, I think Kurumi Ponchio might be the most sexualized song in Vocaloid history, but the others aren't exactly depressing-sad.
